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 are able to use your domain name not just for a site, but also for an instant messaging server, a video streaming host or perhaps a Voice-Over-IP server, for instance, while you still have a site with it. Whenever you set up the SRV record, you can select what Internet Protocol it will use, on which port the connection to the specific server will be established plus the priority and the weight of the record provided that you have a number of SRV records for the exact same service. The latter option allows you to employ 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 if the same one is unable to provide all services that you need.
