An SRV record, which means Service record, is a DNS entry employed to outline the servers which run a certain service for a domain. Quite simply, you’re able to use your Internet domain not only for an Internet site, but also for an instant messaging server, a video streaming host or a Voice-Over-IP server, for instance, while you still have an Internet site with it. If you set up the SRV record, you may choose what Internet Protocol it's going to employ, on which port the connection to the specific server will be established along with the priority and the weight of the record provided that you have several SRV records for the very same service. The latter option will allow you to employ different machines for load balancing and redundancy. With this type of DNS records, you can use the same domain name many different purposes and even with different providers if the same one is unable to provide all services you require.
