An SRV record, which signifies Service record, is a DNS entry employed to define the servers which run a particular service for a domain name. In other words, you can use your domain name not only for a site, but also for an instant messaging server, a video streaming host or a Voice-Over-IP server, for example, while you still have an Internet site with it. If you create the SRV record, you can select what IP 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 you have a number of SRV records for the exact same service. The latter option will permit you to employ different machines for load balancing and redundancy. Using this kind of DNS records, you may use the same domain address for a variety of purposes and even with different companies in case the same one is not able to provide all services you require.
