An SRV record, which means Service record, is a DNS entry employed to identify the servers which run a specific service for a domain. Basically, you are able to use your Internet domain not only 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 a website with it. Whenever you create the SRV record, you can pick what Internet Protocol it is going to use, on which port the connection to the specific server is going to be established along with 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 employ different machines for load balancing and redundancy. With this kind of DNS records, you can use the same domain address many different purposes and even with different providers in case the same one can't provide all services you need.
