An SRV record, which is short for Service record, is a DNS entry that is used to outline the servers which run a particular service for a domain name. Quite simply, you can use your Internet domain not only for an Internet 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 an Internet site with it. If you set up the SRV record, you can choose what IP it will use, on which port the connection to the particular server is going to be established as well as the priority and the weight of the record assuming that you have several SRV records for the exact same service. The latter option will allow you to use different machines for load balancing and redundancy. Using this type of DNS records, you can 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.
