Abstract:
This document offers an approach to initiating TLS for DNS: use of a
dedicated DNS-over-TLS port, and fallback to a mechanism for
upgrading a DNS-over-TCP connection over the standard port (TCP/53)
to a DNS-over-TLS connection. Encryption provided by TLS eliminates
opportunities for eavesdropping on DNS queries in the network, such
as discussed in RFC 7258. In addition it specifies two usage
profiles for DNS-over-TLS. Finally, it provides advice on
performance considerations to minimize overheads from using TCP and
TLS with DNS, pertaining to both approaches.
