An SRV record, which is short for Service record, is a DNS entry employed to identify the servers that run a certain service for a domain name. Quite simply, you are able to use your domain name not just for a site, but also for an instant messaging server, a video streaming host or a Voice-Over-IP server, for example, while you still have a site with it. When you create the SRV record, you can pick what IP it will use, on which port the connection to the specific server will be established as well as the priority and the weight of the record in case that you have several SRV records for the exact same service. The latter option allows you to employ different machines for load balancing and redundancy. Using this kind of DNS records, you may use the same domain for a variety of purposes and even with different companies in case the same one is not able to provide all services you need.
