An SRV record, which means Service record, is a DNS entry employed to identify the servers that run a specific service for a domain name. Basically, you’re able to use your domain not just for a web site, but also for an instant messaging server, a video streaming host or even a Voice-Over-IP server, for instance, while you still have an Internet site with it. When 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 in addition to the priority and the weight of the record provided that you have a number of 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 address for a number of purposes and even with different companies if the same one can't provide all services you need.
