An SRV record, which is short for Service record, is a DNS entry which is used to outline the servers that run a certain service for a domain. Basically, you are 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, as an example, while you still have an Internet site with it. Whenever you set up the SRV record, you can select what IP it'll use, on which port the connection to the specific server will be established as well as the priority and the weight of the record provided that there are several SRV records for the very same service. The latter option will enable you to employ different machines for load balancing and redundancy. With this kind of DNS records, you may use the same domain name many different purposes and even with different companies if the same one can't provide all services that you need.
