all of the DHCP options, for example.
SLAAC just tells the endpoint device to self-assign an address and to roll with it. For example, there’s no way to pass in DNS servers with SLAAC.
- MayeulC 3y agoCan't you provide DNS servers as part of router advertisement packets ? RFC8106
- sgjohnson 3y agoI stand corrected, but I haven't seen this in practice yet.
- magicalhippo 3y agoThis requires client support though, which isn't a given.
- stephen_g 3y agoI expect basically anything that supports SLAAC would have supported DNS advertisements for at least a few years…
- ArchOversight 3y agoThat is most operating systems and devices these days.
- rnhmjoj 3y agoThe DNS bit it's not true: there's RFC8106 [1] for this and it's widely supported. You can set a list of DNS servers to use (RDNSS) and a domain suffix for resolving unqualified hostnames (DNSSL), exactly as for DHCP.
