IPv6 Buzz 121: Uncovering IPv6 Host Default Address Selection

In this episode, Ed, Scott, and Tom explore the topic of default address selection with IPv6 hosts as defined in RFC 6724. It’s very common for a host to have multiple IPv6 addresses of different types (as well as an IPv4 address in dual-stack environments) and RFC 6724 includes rules for which addresses are used first. Topics discussed include: * What’s exactly in RFC 6724 * Which addresses are preferred and why * The prefix policy table * How default address selection impacts host and application behavior * Operational considerations of IPv6 host address selection Thanks for listening!
