A Service record (SRV record) is a specification of data in the Domain Name System defining the location, i.e., the hostname and port number, of servers for specified services. It is defined in RFC 2782, and its type code is 33. Some Internet protocols such as the Session Initiation Protocol (SIP) and the Extensible Messaging and Presence Protocol (XMPP) often require SRV support by network elements.

Usage

SRV records are common in conjunction with the following standardized communications protocols:[clarification needed]

In Microsoft Windows 2000 clients query for SRV records to determine the domain controller for a given service. SRV records are also used by Outlook 2007, 2010 and Macintosh 10.6 mail to locate the Exchange Autodiscover service.[14] In Microsoft Windows networks domain controllers register their network service types for Active Directory in the DNS.

An older version of the Internet Draft for OpenPGP Web Key Directory uses SRV records for discovering OpenPGP keys through web servers.[15] Usages of SRV records are no longer part of the Internet Draft in later versions.[16]

A registry of service names for SRV records & protocols is maintained by the Internet Assigned Numbers Authority (IANA) as defined in RFC 6335.[17]
