An SRV record, which is short for Service record, is a DNS entry employed to outline the servers that run a specific service for a domain. Put simply, you can use your Internet domain not only for an Internet 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 an Internet site with it. If you create the SRV record, you can choose what Internet Protocol it will use, on which port the connection to the specific server is going to be established along with the priority and the weight of the record assuming that there are several SRV records for the exact same service. The second option will enable you to use different machines for load balancing and redundancy. With this type of DNS records, you could use the same domain for a variety of purposes and even with different providers in case the same one can't provide all services that you need.
