An SRV record, which is short for Service record, is a DNS entry employed to define the servers that run a certain service for a domain. Basically, you’ll be able to use your Internet domain not just 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. When you set up the SRV record, you can pick what IP it will use, on which port the connection to the specific server is going to be established as well as the priority and the weight of the record assuming that you have a number of SRV records for the exact same service. The second option will permit you to use different machines for load balancing and redundancy. Using this type of DNS records, you may use the same domain for a variety of purposes and even with different providers if the same one cannot provide all services you require.
