An SRV record, which is short for Service record, is a DNS entry employed to identify the servers that run a certain service for a domain name. Quite simply, you can use your Internet domain not only for an Internet site, but also for an instant messaging server, a video streaming host or a Voice-Over-IP server, as an example, while you still have an Internet site with it. Whenever you set up the SRV record, you may choose what IP it will use, 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 there are several SRV records for the exact same service. The second option will allow you to use different machines for load balancing and redundancy. With this type of DNS records, you may use the same domain address for various purposes and even with different providers if the same one can't provide all services that you need.
