An SRV record, which signifies Service record, is a DNS entry which is used to define the servers that run a certain service for a domain name. Quite simply, you will be able to use your domain name not only 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 an Internet site with it. Whenever you set up the SRV record, you can select what IP it is going to employ, on which port the connection to the specific server is going to be established as well as the priority and the weight of the record assuming that you have several SRV records for the exact same service. The second option will enable 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 variety of purposes and even with different companies if the same one can't provide all services that you need.
