Internet Engineering Task Force (IETF) J. Jeong Request for Comments: 8106 Sungkyunkwan University Obsoletes: 6106 S. Park Category: Standards Track Samsung Electronics ISSN: 2070-1721 L. Beloeil Orange S. Madanapalli NTT Data March 2017 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. Status of This Memo This is an Internet Standards Track document. This document is a product of the Internet Engineering Task Force (IETF). It represents the consensus of the IETF community. It has received public review and has been approved for publication by the Internet Engineering Steering Group (IESG). Further information on Internet Standards is available in Section 2 of RFC 7841.
