What is default IPv6 configuration on routers

bl flag

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?

It depends.

You generally have a few modes:

  1. 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.
  2. DHCP6. Clients get only routes through RA.
  3. 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.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
