An SRV record, which signifies Service record, is a DNS entry that is used to outline the servers which run a specific service for a domain. Basically, you will be able to use your domain name not just for an Internet 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 an Internet site with it. When you create the SRV record, you can select what Internet Protocol it's going to employ, on which port the connection to the specific server is going to be established plus 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 use different machines for load balancing and redundancy. With this type of DNS records, you can use the same domain address for various purposes and even with different providers in case the same one is not able to provide all services you need.
