- DNS RFC Reference
- =================
- The DNS is defined by a large number of RFCs, many of which have been
- extensively updated or obsoleted. This chapter aims to provide a
- roadmap and reference for this confusing space. The chapter does not
- aim to be encyclopedically complete, however, as the key information
- would then be lost in the noise. The curious are encouraged to click
- on the "Updated by" links on the IETF pages to see the finer points, or
- the "Obsoletes" links to go spelunking into the history of the DNS.
- DNSSEC gets its own section instead of being included in the "Core"
- list because there are many DNSSEC related RFCs and it's helpful to group
- them together. It's not a statement that DNSSEC isn't part of the "Core"
- of the DNS.
- The IANA `DNS Parameters <http://www.iana.org/assignments/dns-parameters/dns-parameters.xhtml>`_ registry is the offical reference site for all DNS
- constants.

- RFCs for RR types
- -----------------
- There are many more RR types than are listed here; if a type is not
- listed it means it is obsolete, deprecated, or rare "in the wild".
- Some newer types that are currently rare are listed because they may
- well be more heavily used in the not-to-distant future.
