What is default IPv6 configuration on routers
I've just started learning IPv6. I have a router running OpenWrt and I would like to configure it to use IPv6. As I know this address can be assigning to a client with or without DHCPv6 server. Do you know what is the default configuration on popular routers? Which method is used? Statefull, stateless or statefull + stateless?
Solution 1:
It depends.
You generally have a few modes:
- SLAAC. Clients pick their own IP, based on a announced subnet, which must be a /64. They get subnet and route from the RA announcements.
- DHCP6. Clients get only routes through RA.
- Combination. They may use SLAAC, or DHCP. Either will work, but DHCP may provide additional useful settings.
For a client network, I'd suggest going with SLAAC or SLAAC + DHCP. For servers, it's probably a good idea to not use SLAAC, but stay with DHCP.
