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.

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 ...

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.

It's been a quarter of a century since the first IPv6 standard was finalized as RFC 2460, and to say adoption has been slow is an understatement. The pool of available IPv4 addresses has been ...

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 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 ...

IPv6 vs. IPv4 IPv6 is a “new, reasonably ground-up design of a replacement for IPv4,” Montgomery says. Back in the early 1990s, those watching the nascent internet grow were quick to discern that IPv4 ...

Shortened or not, IPv6 addresses don't lend themselves to easy memorization. Don't fret, though; you can use the same naming conventions for IPv6 as you did for IPv4.

The great migration from IPv4 to IPv6 has officially begun, after ICANN added the first addresses to its root servers that conform to the new version of the internet protocol. On Monday, ICANN ...

IPv6 offers several ways that aren’t possible in IPv4 to assign IP addresses, and DNS set-up has differences as well.

The Internet is running out of IPv4 addresses; there's no argument about that. But what is up for debate is whether ISPs will migrate directly to IPv6 to solve this problem, or whether they will ...

The Number Resource Organization warns that less than 10 percent of the IPv4 address space remains; it's time to start adopting IPv6. The warning comes after APNIC, the registry that hands out IP ...
