So, IANA ran out of IPv4 addresses this year. I want to use that as an opportunity to play with IPv6 and get it working in my network. I think we have a long time before IPv4 truly disappears, but it would be nice to say I’m ready. The goal is the get both my DMZ and my insecure network to only use IPv6 and my main LAN to be dual stack.
Migrating my LAN to IPv6 only will be very challenging since there are a lot of different devices on it and there will be issues getting some things to work together nicely (domain controllers, NAS, Wifi AP’s may not support IPv6 easily) but getting dual stack to work can be a nice short term goal.
For IPv4, I currently have my router NAT’ing private IPs to public IP’s for outgoing traffic. If the router will NAT IPv6 to IPv4 addresses, then those subnets can be IPv6 only and still talk to the rest of the IPv4 internet.
This is a big project, so I’m breaking this in to parts. I’ll update this page as I go forward
- We’ll get two hosts talking on the same subnet
- Next we configure the router to route IPv6 traffic correctly
- We need DNS to work right
