An SRV record, which means Service record, is a DNS entry employed to define the servers that run a specific service for a domain. Put simply, you’ll be able to use your domain not just for a web 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 an Internet site with it. Whenever you create the SRV record, you can choose what Internet Protocol it'll employ, on which port the connection to the particular server is going to be established along with the priority and the weight of the record in case that there are several SRV records for the very same service. The second option allows you to employ different machines for load balancing and redundancy. Using this type of DNS records, you may use the same domain for a variety of purposes and even with different providers if the same one is not able to provide all services that you need.
