An SRV record, which is short for Service record, is a DNS entry which is used to outline the servers that run a specific service for a domain. In other words, you’ll be able to use your domain not just for an Internet site, but also for an instant messaging server, a video streaming host or perhaps a Voice-Over-IP server, as an example, while you still have an Internet site with it. When you set up the SRV record, you can pick what Internet Protocol it's going to employ, on which port the connection to the particular server is going to be established along with the priority and the weight of the record provided that there are several SRV records for the exact same service. The latter option will permit you to employ different machines for load balancing and redundancy. Using this kind of DNS records, you can use the same domain address for various purposes and even with different providers if the same one can't provide all services that you need.
