A lightning fast practical intro to IPv6

Length: 10 minutes

Room: Room 2

Abstract

IPv6 has slowly started to appear and people may be using it without knowing it,... and be baffled when a DNS name resolves to an IPv6 address instead of an IPv4 address and e.g. ping suddenly can't route. This lightning talk aims to help people quickly troubleshoot and work around IPv6 problems they stumble over, explain why there may seemingly be an IPv6 address on your NIC but you still can't route, how to read and understand the cryptic and long hex strings that are IPv6 addresses, what it means if you have multiple IPv6 addresses on a NIC and more. Also a super-brief history lesson and why NAT sidelined IPv6 for so many years, as well as why IPv6 is making a comeback. And about what IPv6 can do that NAT'ed IPv4 can't. Much will be done in a live demo from a GNU/linux bash command line.
