An SRV record, which signifies Service record, is a DNS entry which is used to identify the servers that run a certain service for a domain name. Put simply, you’ll be able to use your Internet domain not only for an Internet site, but also for an instant messaging server, a video streaming host or a Voice-Over-IP server, as an example, while you still have a site with it. Whenever you create the SRV record, you can choose what Internet Protocol it is going to use, on which port the connection to the specific server will be established as well as the priority and the weight of the record provided that there are several SRV records for the exact same service. The latter option allows you to employ different machines for load balancing and redundancy. With this kind of DNS records, you could use the same domain address for a number of purposes and even with different companies if the same one is not able to provide all services that you need.
