An SRV record, which stands for Service record, is a DNS entry employed to outline the servers that run a certain service for a domain name. Put simply, you can use your domain not just for a website, but also for an instant messaging server, a video streaming host or a Voice-Over-IP server, for instance, while you still have a website with it. Whenever you create the SRV record, you can choose what Internet Protocol it will employ, on which port the connection to the specific server is going to be established plus the priority and the weight of the record in case that you have a number of SRV records for the exact same service. The latter option will permit you to employ different machines for load balancing and redundancy. With this type of DNS records, you may use the same domain name for various purposes and even with different providers in case the same one is not able to provide all services that you need.
