An SRV record, which is short for Service record, is a DNS entry employed to identify the servers that run a specific service for a domain name. In other words, you can use your domain name not only for a web 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 site with it. If you set up the SRV record, you can choose what Internet Protocol it is going to employ, on which port the connection to the specific server is going to be established in addition to the priority and the weight of the record in case that you have several SRV records for the exact same service. The latter option will enable you to use different machines for load balancing and redundancy. With this kind of DNS records, you may use the same domain for various purposes and even with different companies in case the same one cannot provide all services you need.
