An SRV record, which is short for Service record, is a DNS entry which is used to define the servers that run a particular service for a domain name. Quite simply, you will be able to use your domain not only for a website, but also for an instant messaging server, a video streaming host or perhaps a Voice-Over-IP server, as an example, while you still have a website with it. If you create the SRV record, you may choose what IP it is going to employ, on which port the connection to the specific server is going to be established in addition to 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 allow you to employ different machines for load balancing and redundancy. With this kind of DNS records, you can use the same domain name for various purposes and even with different providers if the same one is unable to provide all services you require.
