What are IPv4 and IPv6?

IPv4 and IPv6 are IP addresses that are binary numbers. IPv4 is a 32-bit binary number, and IPv6 is a 128-bit binary number address. IPv6 offers better security and more efficient connections.

What are IPv4 & IPv6?

IPv4 and IPv6 are IP addresses that are binary numbers. IPv4 is a 32-bit binary number, and IPv6 is a 128-bit binary number address. IPv6 is the sixth revision to the Internet Protocol and the successor to IPv4, and offers better security and more efficient connections

IPv4 and IPv6 are two different types of network addresses. The internet is a global network, and it requires that every device on the internet has an address to communicate with other devices. So how does this work? You can think of IP addresses as your home’s postal address – except you need one for each device!

IPv6 (Internet Protocol version 6) is the sixth revision to the Internet Protocol and the successor to IPv4 (Internet Protocol version 4). IPv6 can add support for more devices, better security, and more efficient connections.

When we talk about IPv4 vs IPv6, we’re talking about which type of protocol (or system) is used to assign these unique numbers. It includes Network address translation for internet protocol security with specific internet addresses.

IPv4 is the older version of IP addressing that was created in 1981. IPv6, on the other hand, was developed in 1998 and is a much more modern protocol. It can produce an incredible amount of addresses (340 undecillion) while still being compatible with today’s technology. If you’re curious about what these two protocols are and how they differ from each other, read on for all the details!

 How do ipv4 and ipv6 works?

The Internet is run by the IP protocol (Internet Protocol). This protocol defines how systems communicate with each other and it uses 4 numbers separated by dots. Each number is called an ‘octet’ and can range from 0 to 255. The first octet of an IP – version 4 (ipv4) address is the network id and the last 3 octets are a host id. The connectionless protocol comes with a numeric address resolution protocol for forwarding routes.

ipv4 uses 32 bits to represent each address, which means that there can be 2^32 hosts on a single ipv4 network (this is equal to around 4.29 billion or 429 million). That was not enough for the internet as grown, so a new standard emerged – ipv6. An alphanumeric address will let you work through the internet engineering task force for a numerical IP address.

In this primary internet protocol, there are 8 groups of digits separated by colons instead of dots. Each group has 16 bits and also it uses 128 bits to represent the entire address. This allows for a maximum of 340 trillion hosts on a single ipv6 network (340×10^38). Every computer, mobile phone, home automation component, IoT sensor, and any other device connected to the Internet.

Differences Between IPv4 and IPv6 Addresses

ipv4 vs ipv6

There are many differences between IPv4 and IPv6. Some of the differences identified below might be out-of-date since this document was last updated in 2002 (it is currently 2010). However, hopefully, you will find this information useful if you want to learn something about networking. Connectionless Protocol Allows creating a simple virtual communication layer over diversified devices.

IPv4 makes use of 32-bit addresses, which can be written in dotted decimal notation, for example, Each part of the address represents 8 bits (octets) of data so each address consists of 4 octets or 32 bits total with one reserved as a network identifier, leaving three undifferentiated octets for determining host identifiers within networks.

IPv6 uses 128-bit addresses. The IPv6 address space consists of 2 ^ 64 (about 18.4 * 10^38) addresses, which is about 340 undecillion (340 * 10^36) or 340 billion billion billion. Like IPv4, each part of the address represents 8 bits (octets) of data so each address consists of 4 octets or 32 bits total.

IPv4 makes use of a three-layer network design that includes the designation of a network identifier and host identifiers within each network. The network prefix is the combination of a subnet identifier and a subnet mask which represents a contiguous sequence of all 1s for the bit positions set to1 in the mask, followed by all 0s for the bit positions set to 0 in the mask.

Other Layer Two Tunneling Protocol features

include path MTU discovery and the ability to carry data links that the Internet Protocol does not support, such as token ring and DECnet.

The Layer Two Tunneling Protocol is a method for transporting layer 2 “circuits” across an IP-based network; usually over the internet. It can be used to allow communications between two nodes on a packet-switched network even if the networks in question use different Layer 2 protocols.

Ipv4 is a networking protocol that allows computer-to-computer communications across an internet connection. It serves as the best option for basic web browsing and file downloads but can be very limiting when trying to play online games or video chat with friends. Ipv4 is generally considered outdated and less efficient than the newer Ipv6 protocol.


IPv4 and IPv6 are the protocols that determine how devices connect to a network. They don’t have much in common other than their names, so it’s important to know which one you’re using before connecting your device. Most people have been using IPv4 for years without knowing what it was called, but now is the time to make the switch!

IPV4 stands for Internet Protocol Version 4. IP is an addressing system that allows devices to communicate on the internet. IPv6 stands for Internet Protocol version 6, which is the next generation of IP addresses. IPv6 is designed to be more efficient and scalable than its predecessor in order to serve a rapidly growing number of connected devices.
