What are different IP versions?

There are two versions of IP that currently coexist in the global Internet: IP version 4 (IPv4) and IP version 6 (IPv6). IP addresses are made up of binary values and drive the routing of all data over the Internet. IPv4 addresses are 32 bits long, and IPv6 addresses 128 bits long.

Why are there different versions of IP?

Version Numbers Each version of IP has a separate Layer 2 Protocol Number assigned. Packets from one IP version cannot be understood by a host running exclusive a different IP version. e.g. A host which only knows IPv4 cannot usefully exchange packets directly with a host which only speaks IPv6.

What are the two IP versions?

There are two IP versions: IPv4 and IPv6. IPv4 is the older version which has a space of over 4 billion IP addresses. However, the new IPv6 version can provide up to trillions of IP addresses to fulfill the need of all internet users and devices.

What are the different versions of the IP address?

There are two versions of IP address. Internet Protocol Version 4 (IPv4) was the initial version, which is still widely used by most of the websites on the Internet. It has a size of 32 bits and holds 2 32 numbers equals to 4,294,967,296. The depletion of numbers on IPv4 forced authorities to introduce another Internet Protocol Version 6 (IPv6).

What is the version number of IPv4?

Packets that hold Internet Protocol data carry a 4-bit IP version number as the first field of its header. Currently, only IPv4 and IPv6 packets are seen on the Internet, having IP version numbers 4 and 6, respectively.

Which is the latest version of Internet Protocol?

Due to the difficulties associated with making such an important change, development of this new version of IP has actually been underway since the mid-1990s. This new version of IP is formally called Internet Protocol version 6 (IPv6) and also sometimes referred to as IP Next Generation or IPng.

What is the size of an IP address?
