ipv6 for christmas

there’s really almost nothing much simpler than starting to use IPv6.

first of all, all major OS support IPv6 today. most of them are running it out of the box.

second of all, tunnel brokers are available everywhere, so while i haven’t had luck with sixxs (they didn’t respond after weeks of waiting), using Hurricane Electric was easy and took like seconds. friendly “wizard” will walk you through and then even show example of configuration for your device. you’ll get your own /64 (freebie under Christmas tree!), and option to request additional /48. should be enough even for bigger home labs :)

for ‘home usage’ it’s worth to note, that Cisco IOS doesn’t support IPv6 yet in Zone-Based Firewall (ZBFW), so you need to use Context-Based Access Control Firewall (CBAC).

as soon as you’ll ping ipv6.google.com, www.kame.net and some sites that show your IPv6 connectivity, it’s good to take a step back and re-thing your connectivity. it’s not only about security (there’s no NAT!) but also QoS, addressing plan… exactly the thing you can do during long winter evenings :)
