Beloeil France Telecom R&D S. Madanapalli iRam Technologies June 14, 2016 IPv6 Router Advertisement Options for DNS Configuration draft-ietf-6man-rdnss-rfc6106bis-14 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 obsoletes RFC 6106 and allows a higher default value of the lifetime of the DNS RA options to avoid the frequent expiry of the options on links with a relatively high rate of packet loss.
