An SRV record, which means Service record, is a DNS entry that is used to identify the servers which run a particular service for a domain name. Put simply, you’ll be able to use your domain not just for a 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 a site with it. When you create the SRV record, you can select what IP it will employ, on which port the connection to the particular server is going to be established as well as the priority and the weight of the record assuming that you have several 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 address for a number of purposes and even with different providers if the same one can't provide all services you need.
