What is an IP Address?

An “Internet Protocol” IP address is a unique numerical address that identifies a device or a server on the internet or a local network.

what is ip address

An IP address, Internet Protocol address, is a unique identifying number for network hardware, devices and servers connected to a network.

The Internet Protocol address or IP address is a numeric label assigned to each device participating in a computer network. It serves two purposes: identification of the host and location addressing. The IP address provides an identifier for computers on networks to communicate with other hosts and locate services.

In web hosting it's advantageous to have a dedicated IP address because it gives your hosting account and website a unique IP address, one that's not being shared by any other accounts on the server. Most dedicated server hosting and VPS hosting companies provide dedicated IPs.

An IP address also helps determine how data reaches its final destination from the point it leaves one system to go between otherIP stands for Internet Protocol. IP works to differentiate between your computer and others on the network. Your IP address is unique to you, so it's also called a “computer's identity.” You are assigned an IP by your internet service provider or mobile carrier when you connect to the Internet.

An IP address is a unique number that identifies your device on the Internet. It's similar to an address of home or business, which you find on every letter that comes in the mail. Your IP address tells other devices where to send information destined for your computer. For example, when you request web pages from your browser, they are sent back with their unique IP addresses so that the pages can be displayed correctly. The external IP address offers options to the local network and helps get maximum benefits.

How to Identify my IP address?

The same IP address is like your home address, which tells others where to send information.

Most people think that your IP Address is the same as the one assigned by your ISP (Internet Service Provider). However, it's easy to determine whether this is true or not.

To do so, there are free services that will tell you what IP address they see when you visit them in a browser.

When running these services, you might get a warning message that says: “Your IP address is not linked to a hostname.” This usually happens when your ISP uses dynamic IP addresses. These are temporary IPs that might change at any time, so the website sees them as unidentified IPs. That's why these incidents don't usually matter.

By following this guide, you should know what IP Address you are using. If your ISP gives dynamic IPs, then be sure to check back periodically to see if your IP changes have taken place.

What is IPv4?

The IPv4 is a connection that allows to connect to an internet network and access the Internet. The IPv4 has a unique number, and it is similar to a house address or phone number. This can identify your computer on the Internet so that other computers may contact yours. Besides this, the Internet Protocol Version 4 (IPv4) is a set of rules that allow sending data over the network. This protocol divides the information into small blocks, and every league has a generous size.

IPv4 works with 32 bits addresses; it uses a combination of 4 numbers from 0 to 255 in decimal notation. For example, 192.168.1.1 is an IPv4 address. To create an IPv4 address, the combination of numbers must be divided into four octets.

Every host on the Internet has at least one IPv4 address assigned. If you connect your computer to the Internet, it will receive a unique IPv4 address. You can find this number in the properties of your wifi's connection, where it says ‘IPv4 address'.

On an IPv4 network, 255.255.255.255 is a broadcast address that means every host on the current major network will receive the packet. Besides this, 0.0.0.0 is also a broadcast address because it is a particular type of network by default. The IPv4 protocol does not allow the broadcast of packets on a smaller subnet than 255.255.255.0.

Advantages of own IP address

IPv4 is the fourth version in the development of internet protocol (IP), and it's currently used for wide area networks (WAN), local area networks (LAN), and wireless connections. It allows users to communicate via physical and virtual networks, such as local area and metropolitan networks, spread over large geographical distances.

IPv4 defines an IP address as a 32-bit number, and it's usually written in quad-dotted decimal notation. An IP address, such as 192.168.0.1, is unique and has two parts: network id and host id. The network id can identify the type of computer network, and the host id can identify a specific computer on that network.

IPv4 uses 4 bytes (32 bits) to define an IP address. When written in decimal, each byte is composed of 8 bits, meaning there are 256 possible values for each byte since 2^8 = 256. This means there must be at least ~4.3 billion separate IP addresses.

IPv4 is currently the most widely used IP version because it has enough IP address space to allow billions of devices. It's expected that IPv4 addresses will be exhausted in 2010 or 2011 when IPv6 must take its place.

What is IPv6?

Ipv6, short for internet protocol version 6, is the next generation of IPs. A new set of addressing and routing protocols replaces the currently used IPv4.

IPv6 was designed to respond to the impending address exhaustion of IPv4. The number of computers, mobile phones, and other devices using the Internet has been growing at an incredible pace. It is expected that by 2020 there will be 50 billion interconnected devices. This is more than six times the number of devices connected to the Internet today.

Advantage of static IP addresses

To accommodate the rapid growth of IPs, IPv6 provides many advancements over IPv4. These include security features such as stateful firewalls and IPSec, mobility features such as Mobile IP, simpler autoconfiguration for computers and mobile phones, and better. In 1998, the internet industry began a concerted effort to complete the IPv6 standard and migrate from our existing protocol.

A collaborative effort was begun with IETF (Internet Engineering Task Force), a US-based group that defines standards for IPs and IP communications. Currently, there are several hundred organizations worldwide participating in this effort. ipv6 also increases the size of subnets from 32 bits to 128 bits. This huge address pool has provided enough space for every molecule on earth to address and still leaves room for expansion. ‘

With IPv4, we had only about 4 billion potential networks where each network could accommodate up to 256 devices. The number of addresses available in IPv6 is 2128 or 3.4×1038 unique addresses. These particular addresses are enough for every device to have about 100 million IPs each and still leave room for expansion.

What is a dynamic IP address?

Dynamic IP address means a changing IP address. This change in the IP address is not random but changes according to a schedule. An active IP address can start at one number, and after a certain amount of time, it will switch over to another. Dynamic addresses are often seen on companies' networks, where multiple computers share a connection to an internet service provider. Another everyday use of dynamic IP addresses is on home networks where several computers share an internet connection. Still, they are behind a router or modem that connects to the Internet wirelessly.

Dynamic IP addresses can also change on some routers by themselves periodically; this is called DHCP (dynamic host configuration protocol).; this is often with wireless routers. For instance, you might set your IP address to 192.168.0.100, but after an automatic update, perforce will always be able to connect to the Internet without worrying about IP addresses.

IPv6 uses smaller address blocks than IPv4, making the routing tables more efficient and reducing network traffic on transit networks significantly. Finally, IPv6 is a more straightforward protocol than IPv4 and requires less processing power to route packets through the web because the header contains less information.

What is a static IP address?

A static IP is one that you manually assign by entering the correct network settings in your operating system (i.e., Windows). A static IP isn't given to you automatically; instead, you need to define it yourself using the appropriate window (or configuration tool) provided with your operating system. A static IP can also be used to host your website or other servers because the exact number will always correspond to the same device, ensuring that messages addressed to that specific address will reach it.

A static IP address is a unique set of numbers that identifies your computer on the Internet. When you're connected to the Internet, your router forwards incoming.

A static IP is not the same as a Dynamic Host Configuration Protocol (DHCP) address, which your ISP supplies whenever you sign up for service. A DHCP address can change on occasion, but it's more likely that your router will continue to assign the same one every time it looks into connecting to your modem.

It's also possible to have a static IP address assigned by an ISP, but this is not recommended for home users. A static IP will work well enough in some cases, but it can become problematic if you want to retain access when your IP changes (which might happen for many reasons). Because ISPs allocate IPs dynamically, it will be difficult, if not impossible, to continue using your website or email when you get a new IP address.

The best possible configuration for home users is to use DHCP, which automatically assigns an IP to your router whenever you connect. The dynamic nature of DHCP also makes it ideal for mobile devices like WiFi-only iPads, since the address can change without causing any issues.

If you need a static IP, the best option is to get one from your ISP. Many providers will rent out a single address for a small fee – perhaps between $1 and $5 per month – but again, these users should probably opt instead for DHCP.

What is a private IP address?

A private IP address is a dedicated range of IP addresses assigned to a specific organization or company by its Internet service provider (ISP). The ISP will allocate the same amount of dedicated IP addresses until the entire network is covered correctly. Suppose a whole country, state, or city has only one public and one private IP address range. In that case, anyone can easily use the Internet to find and hack into vulnerable servers, computers, and devices connected to that network.

The good thing about private IP addresses is outside sources cannot find them, and they can only be used within your entire computer network. The bad thing is the limited amount of IPs you receive from your ISP since this number will not be enough if you have a big company.

What are the benefits of using a private IP address?

The benefits of using a private IP address range include privacy, security, and safety for your company. Once you have assigned the entire dedicated range to different servers and devices in your network, hackers won't find them because they cannot detect your private IPs on the web, and even your ISP won't be able to see them. You can also use personal IP address ranges on different subnets, allowing you to utilize your entire public IP address range completely.

What is the difference between a private IP address and a dynamic IP address?

Unlike a static IP, or a private one, that is assigned to each device in your computer network; a dynamic IP can change its location because it is linked to the ISP generally. An active public IP address may be assigned to you by your ISP but not permanently. They will usually hand out new public addresses whenever yours has already been used to commit Internet crimes or if it has become inactive for some reason. You can stop these changes using a proxy or a VPN in your router.

What devices can use a private IP address?

Computers, routers, servers, and other computer hardware connected to the Internet can benefit from having a dedicated private IP address range. Servers will usually have fixed personal IP addresses, while computers will change them depending on their network settings.

How do private IP addresses look like?

Private IP addresses have been classified into 3 types depending on their ranges: 10.0.0.0 – 10.255.255.255 172.16.0.0 – 172.31.255 .254 192 . 168 . 0 . 0 – 192 . 168 . 255. 255

You can quickly identify a private IP address because it contains numbers and dots. On the other hand, a public IP is different and looks like this: 123. 456. 789. 001.

What is a public IP address?

A public IP address is a unique string of numbers that allows information to be transmitted from your device(computer, tablet, phone) through the Internet. The IP address helps you identify and locate a particular computer or device on the Internet so you can share files, visit pages or download content.

What does a public IP address look like?

An IP address is a series of four digits separated by three dots in the most common form. Each set of numbers can be deciphered to represent a number between 0 and 255.

For example, the zoom by the ocean website has this IP address: 191.238.224.214. You can see that each section represents a number between 0 and 255 which can be decoded to represent the numbers 191, 238, 224, and 214.

What are the benefits of using a public IP address?

  • To access services over the Internet from anywhere in the world. Public IP addresses are necessary to allow communication between two servers on different networks with no interference from a third party.
  • Public IP is used for accessing your instances .- Going global with your website requires a public IP address.
  • Most of the games on the Internet require a public IP address to give you access to the game.
  • A public IP address is used in some specific cases where we need to access private resources outside our network. For example, one of my clients uses RDS (SQL) over the Internet, and he needs to access this database from outside of his network. For that, he has assigned a public IP for RDS so that anyone connecting to his database can be assured of reaching the correct destination.
  • A VPN concentrator needs a static public address to configure the incoming connection; otherwise, it will not work.
  • Sometimes in a web hosting scenario, if the customer has no static Public IP address, then there is a possibility that when he logs back to his c panel from any other internet connection, the server may not be accessible. In such cases, we have to assign a public IP address to that c panel always to resolve different users on the server.
  • A static public IP address is required for SMTP, POP3, and IMAP mail services.

What devices can use a public IP address?

This question isn't as easy to answer as it may seem. The public IP address is not something that devices or computers are required to have.

Instead, the IP address is more of a field in the device's configuration, which might be filled with an IP address. Many things can use this field, so it isn't possible to list absolutely all of them here. Some examples include:

  • Computers (Desktops, Laptops, Servers)
  • Game Consoles (XBOX, Playstation)
  • Cable/Satellite Set-top boxes
  • Network Attached Storage devices
  • Web Cameras (Not the security kind. Regular cameras that can connect to a network.)
  • Many other kinds of devices.

The public IP address is a configured field that can be filled with an IP address that allows devices to communicate through the Internet Protocol. The list of things that can use a public IP address is very long, but it doesn't include anything alive and somewhat intelligent (e.g., humans).

Bottom line

Every single device connected with a network is assigned an IP address, be it a laptop's IP address or phone's. Your wifi router has an IP address as well. So, this unique set of numbers that identify a piece of internet-connected hardware is what we call the IP address. This number is also how our browser knows which server to connect with when you type in a website's URL.

IP stands for Internet Protocol, and it is the electronic code that allows your computer to communicate on the web. The IP address identifies where data (i.e., information like chat messages, emails, pictures) is sent on an Internet Protocol network (e.g., the Internet).
