An SRV record, which signifies Service record, is a DNS entry employed to define the servers that run a specific service for a domain. Quite simply, you can use your domain name not just for a web site, but also for an instant messaging server, a video streaming host or perhaps a Voice-Over-IP server, as an example, while you still have an Internet site with it. If you set up the SRV record, you may choose what Internet Protocol it will use, on which port the connection to the specific server is going to be established as well as the priority and the weight of the record provided that you have a number of SRV records for the very same service. The second option will permit you to use different machines for load balancing and redundancy. Using this kind of DNS records, you can use the same domain name many different purposes and even with different companies in case the same one can't provide all services you need.
