SRV Records differ from the other DNS records in that they concern the separate domain services and are not related directly to the DNS server.
SRV Records Overview
With the advance in server technologies and the consequential increase in the possibilities for domain owners to control their domains, it has become a matter of competitiveness for hosting providers to offer enhanced DNS management services to customers. DNS control is considered as the most important option for managing domain name's status and behavior on the net.
While most of the DNS control options concern records related directly to the DNS server such as the MX and A records and the CNAME Records, there are also DNS records, such as the SVR Records, which concern the separate domain services.
What are SRV Records?
SRV Records stand for Service records and represent a category of data in the Domain Name System (DNS) responsible for localizing specific services related to domains such as FTP and SIP. They are aimed at further extending the functionality of the standard DNS record types, which basically deal with the ‘machine' side of the DNS management process.
SRV Records Use
One of the most popular uses of SRV Records is to allow location of the service endpoint for a certain domain name in different new Internet protocols such as SIP and XMPP. For that reason, they require that web browsers support SRV Records. With the help of the SRV Records, providers of VOIP and other specific services can specify a port and other specific system information related to their offerings.
SRV Records Format
An SRV Record usually represents a string of parameters, including Service (the name of a certain service), Proto (the service protocol), Name (the desired domain name), TTL, DNS Class, Priority (the target host priority), Weight (a relative weight for records with the same priority), Port (the service's port), Target (the canonical hostname of the server providing the service)_Service._Proto.Name TTL Class SRV Priority Weight Port Target
How to edit SRV records
Editing SRV Records is made remarkably easy through the user-friendly Custom DNS Records management interface integrated into the Control Panel coming with all NTC Hosting plans. Now you can make any desired changes to your SRV Records, by simply selecting the domain name you wish to apply SRV updates for and specify the necessary parameter values.
