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.

Day One: Advanced IPv6 Configuration is a sequel to my first book, Day One: Exploring IPv6, and picks up right where it left off. Namely with BGP. In addition to a fairly thorough look at BGP (iBGP and eBGP / native IPv6 peering and sharing IPv6 routes over IPv4 peering), the book jumps into a few of the additional and often overlooked aspects of deploying an IPv6 network. This includes a look into topics and tools including VRRP, ICMPv6 rate limiting, CoS, IPv6 path MTU discovery, DHCPv6, zero hop-limit, Multicast Listener Discovery (MLD) and Duplicate Address Detection (DAD).
