An SRV record, which signifies Service record, is a DNS entry that is used to define the servers that run a particular service for a domain. Put simply, you can 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, for instance, while you still have an Internet site with it. Whenever you create the SRV record, you can pick what IP it's going to employ, on which port the connection to the particular server is going to be established in addition to the priority and the weight of the record provided 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 kind of DNS records, you may use the same domain many different purposes and even with different companies if the same one is not able to provide all services that you need.
