An SRV record, which is short for Service record, is a DNS entry that is used to outline the servers which run a particular service for a domain name. Quite simply, you’ll be able to use your Internet domain not just for a website, 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. When you set up the SRV record, you can choose what Internet Protocol it's going to employ, on which port the connection to the specific server will be established as well as the priority and the weight of the record assuming that you have several SRV records for the exact same service. The latter option allows you to employ different machines for load balancing and redundancy. Using this type of DNS records, you may use the same domain address many different purposes and even with different providers if the same one cannot provide all services you require.
