An SRV record, which means Service record, is a DNS entry which is used to outline the servers that run a particular service for a domain name. Quite simply, you’re able to use your Internet domain not only for a web site, but also for an instant messaging server, a video streaming host or even a Voice-Over-IP server, for instance, while you still have an Internet site with it. If you create the SRV record, you can select what Internet Protocol it is going to use, 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 allows you to use different machines for load balancing and redundancy. With this type of DNS records, you may use the same domain name for a variety of purposes and even with different providers if the same one is unable to provide all services you need.
