An SRV record, which stands for Service record, is a DNS entry that is used to define the servers that run a certain service for a domain. Quite simply, you’ll be able to use your Internet domain not only for a web site, but also for an instant messaging server, a video streaming host or perhaps a Voice-Over-IP server, for example, while you still have a site with it. When you create the SRV record, you may choose what Internet Protocol it will use, on which port the connection to the specific server is going to be established along with the priority and the weight of the record assuming that there are several 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 for a number of purposes and even with different companies in case the same one is not able to provide all services that you need.
