The address space is the main difference between IPv4 (32-bit) and IPv6 (64-bit). The text representation has also been changed from a 2-digit partitioning for IPv4 to 4-digits for IPv6.

The problem that the IETF is facing is that, despite the family resemblance, there is a very fundamental difference between IPv4 and IPv6: IPv4 uses 32-bit addresses, while IPv6 uses 128-bit ...

It’s no news that the Internet, which currently runs on internet protocol version 4 (IPv4), has a limited number of IP addresses available, and has already fallen short to suffice the needs of ...

If you are using Internet or almost any computer network you will likely using IPv4 packets. IPv4 uses 32-bit source and destination address fields. We are actually running out ...

The IPv4 era is well and truly over as the Internet Architecture Board has said all IPv4 addresses have been allocated.

Migration has been gradual, but the move to IPv6 could speed up with IPv4 addresses running out The argument about how best to upgrade the Internet’s main communications protocol raged in the ...

Here’s what they did: 1. BUILT A LARGER ADDRESS SPACE. The length of an IP address in IPv6 is 128 bits. That’s four times the size of the IPv4 address making for a total of 3.4×1038 addresses ...

A new protocol, IPv6, was devised and hailed as the solution, with exhaustion of IPv4 addresses leading many to expect IPv4's replacement within a decade.

IPv6 takes one step forward, IPv4 two steps back in 2012 IPv6 rollout is still inefficient with problems ahead, but there is slow progress.

The near-exhaustion of IPv4 addresses is a cause for concern but not panic as new technologies are helping service providers transition to IPv6, Brocade said.
