An SRV record, which is short for Service record, is a DNS entry employed to identify the servers which run a specific service for a domain. Put simply, you can use your domain not only for a web site, but also for an instant messaging server, a video streaming host or perhaps a Voice-Over-IP server, for instance, while you still have a site with it. If you set up the SRV record, you can select what Internet Protocol it will use, on which port the connection to the particular server will be established in addition to the priority and the weight of the record assuming that you have several SRV records for the very same service. The second option will allow you to use different machines for load balancing and redundancy. Using this kind of DNS records, you could use the same domain for a number of purposes and even with different providers in case the same one cannot provide all services you require.
