An SRV record, which is short for Service record, is a DNS entry employed to define the servers which run a certain service for a domain. Basically, you’ll be able to use your domain name not just for a site, but also for an instant messaging server, a video streaming host or a Voice-Over-IP server, as an example, while you still have a site with it. If you create the SRV record, you can select what Internet Protocol it is going to employ, 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 in case that there are several SRV records for the exact same service. The latter option allows you to use different machines for load balancing and redundancy. With this type of DNS records, you can use the same domain for various purposes and even with different providers in case the same one is unable to provide all services you need.
