Introducing IPv6 | Classifying IPv6 Addresses

As with IPv4, an IPv6 address serves as an identifier for an interface or group of interfaces. Also like IPv4, IPv6 addresses come in several types, based on how they represent those interfaces. IPv6 has three types of addresses. This post covers all three, plus some special purpose addresses as well.

Introducing IPv6 | Understanding IPv6 Addresses

The primary difference between IPv4 and IPv6 addresses is length. IPv4 addresses are 32 bits long and IPv6 addresses are 128 bits long. This means that an IPv4 address is made up of 32 1s and 0s while an IPv6 address is made up of 128 of them – 128 binary digits. This massive length forces IPv6 addresses to be written using a different notation than IPv4 addresses and thus makes them very easy to distinguish from IPv4 addresses.

IPv6, A Numbers Game

I was planning on writing this great breakthrough piece on IPv6 subnet sizes, like how many /48s are in a /32 or how many /56s are in a /24, etc… But then I stumbled across a great PDF from ARIN and realized that all the work was already done. So I ended up not posting […]
