Abstract

   This document describes a DNS RR which specifies the location of the
   server(s) for a specific protocol and domain.

Overview and rationale

   Currently, one must either know the exact address of a server to
   contact it, or broadcast a question.

   The SRV RR allows administrators to use several servers for a single
   domain, to move services from host to host with little fuss, and to
   designate some hosts as primary servers for a service and others as
   backups.

   Clients ask for a specific service/protocol for a specific domain
   (the word domain is used here in the strict RFC 1034 sense), and get
   back the names of any available servers.

   Note that where this document refers to "address records", it means A
   RR's, AAAA RR's, or their most modern equivalent.

Podle mne se jedna o jakesi rozsireni systemu IP -> hostname -> RR. Smyslem je asi zrusit DNS zaznamy typu www CNAME stary-server. Protoze stary-server je nazev stroje a www je nazev sluzby.

Proste kdyz budete chtit web firmy XY, tak nemusite premyslet, jestli www.XY nebo XY nebo web.XY. Proste reknete "_http" pro "XY" a vam se vrati ten spravny FQDN.
