IPv6 Router Advertisement Options for DNS Configuration
Abstract
This document specifies IPv6 Router Advertisement (RA) options
(called "DNS RA options") to allow IPv6 routers to advertise a list
of DNS Recursive Server Addresses and a DNS Search List to IPv6
hosts.
This document, which obsoletes RFC 6106, defines a higher default
value of the lifetime of the DNS RA options to reduce the likelihood
of expiry of the options on links with a relatively high rate of
packet loss.
