An SRV record, which signifies Service record, is a DNS entry employed to identify the servers which run a certain service for a domain. Put simply, you can use your Internet domain not only for a website, 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. If you create the SRV record, you can pick what Internet Protocol it will employ, on which port the connection to the particular server will be established along with the priority and the weight of the record in case that you have several SRV records for the very same service. The latter option will allow you to employ different machines for load balancing and redundancy. Using this kind of DNS records, you may use the same domain name for a variety of purposes and even with different providers if the same one cannot provide all services that you need.
