An SRV record, which means Service record, is a DNS entry that is used to identify the servers that run a specific service for a domain name. In other words, you are able to use your domain not only for a website, 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 a website with it. If you set up the SRV record, you can select 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 permit you to employ different machines for load balancing and redundancy. With this type of DNS records, you can use the same domain name for a number of purposes and even with different companies if the same one can't provide all services you need.
