Domain Name System Search List

Domain Name System Search List (DNSSL) is an IPv6 router advertisement (RA) option that allows IPv6 devices to advertise domain names of DNS suffixes to IPv6 hosts in a local area network.

The domain names that are advertised by routers are sent through RA messages to IPv6 hosts. The DNSSL option is supported only when IPv6 routing is active on the network.
