IPv6

In IPv6, the address size has been increased from 32 to 128 bits. The primary difference is not to increase the number of available addresses, but to allow routing nodes a sufficient number of routing prefixes. The readable format of an IPv6 address is broken into eight groups of 4 Hexadecimal digits, with each group representing 16 bits (two octets). An example IP might look like "3ffe:1900:4545:3:200:f8ff:fe21:67cf".

Reserved addresses listed in RFC 5156.
