An SRV record, which means Service record, is a DNS entry employed to outline the servers which run a specific service for a domain. Quite simply, you will be able to use your domain not just for a web 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 website with it. When you create the SRV record, you can pick what IP it will employ, on which port the connection to the specific server will 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 second option will allow you to employ different machines for load balancing and redundancy. Using this type of DNS records, you may use the same domain address for a number of purposes and even with different providers if the same one cannot provide all services that you need.
