Yes, I’ve set myself out to learn IPv6. I thought it was simple – or at least with my understanding of IPv4. I was completely wrong! IPv6 has a much more complicated addressing scheme and “rules”. It requires a change of mindset for a start. The worst part? Getting it all to tunnel through IPv4 when you’re running dynamic IP.<\/p>\n
Anyhow, I’ve got my Linux (CentOS 5) box working and my home network is now “IPv6 ready” (hooray!) but I’m still tweaking the settings so I’ll update the technical stuff later.<\/p>\n
Some little bits about IPv6 I’ve learnt so far is that DHCP servers aren’t really required anymore. Interfaces can self-assign an IP based on their MAC address and this will be almost certainly unique (since MAC addresses are unique). Even in a controlled network, the interface would assign it’s own address.<\/p>\n
Meanwhile, here’s my traceroute to ipv6.google.com. \ud83d\ude00<\/p>\n

I’ve also masked my internal LAN IP to XXXX:XXXX:XXXX otherwise somebody could connect back to my LAN segment. I haven’t had time to figure out the firewall yet. But you can say this is the beauty of IPv6. With a 128 bit address space, every machine has a public routable address.<\/p>\n
Once I have my home network all ready I will begin transitioning all my servers to IPv6. Embrace technology.<\/p>\n","protected":false},"excerpt":{"rendered":"
