An SRV record, which means Service record, is a DNS entry employed to identify the servers that run a particular service for a domain. Quite simply, you will be able to use your domain name not just for a website, 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 website with it. If you create the SRV record, you can pick what IP it is going to employ, on which port the connection to the specific server will be established plus the priority and the weight of the record assuming that you have a number of SRV records for the exact same service. The latter option will permit you to employ different machines for load balancing and redundancy. Using this type of DNS records, you may use the same domain address for various purposes and even with different companies if the same one can't provide all services you require.
