An SRV record, which signifies Service record, is a DNS entry which is used to identify the servers which run a certain service for a domain name. Put simply, 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, for instance, while you still have a site with it. When you create the SRV record, you can pick what IP it will employ, on which port the connection to the specific server will be established as well as the priority and the weight of the record assuming that there are several SRV records for the exact same service. The latter option will permit you to use different machines for load balancing and redundancy. Using this kind of DNS records, you may use the same domain name for various purposes and even with different companies in case the same one cannot provide all services that you need.
