An SRV record, which means Service record, is a DNS entry employed to identify the servers which run a particular service for a domain name. Quite simply, you can use your Internet domain not just for a website, 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 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 in case that there are several SRV records for the very same service. The latter option will permit you to employ different machines for load balancing and redundancy. Using this kind of DNS records, you can use the same domain name for various purposes and even with different companies if the same one is not able to provide all services that you need.
