An SRV record, which signifies Service record, is a DNS entry employed to identify the servers which run a specific service for a domain. Put simply, you are able to use your Internet domain not just for a web site, but also for an instant messaging server, a video streaming host or even a Voice-Over-IP server, as an example, while you still have a site with it. Whenever you create the SRV record, you can pick 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 assuming that you have a number of SRV records for the exact same service. The second option will permit you to use different machines for load balancing and redundancy. With this kind of DNS records, you could use the same domain name for various purposes and even with different providers in case the same one is unable to provide all services you need.
