IPv6 Buzz 088: Host OS IPv6 Addresses – What’s Up With That?

In this episode Ed, Scott, and Tom chat about IPv6 addresses on host OSes: the different types, how they are formed, what they look like, how to tell them apart, and how they are used. Topics discussed include: * Link-local and Global Unicast IPv6 addresses and their different scopes * The IPv6 Interface Identifier (IID) * The difference between Modified EUI-64 and random IIDs * What Router Advertisements do (and how they affect IPv6 address formation) Thanks for listening!
