An SRV record, which is short for Service record, is a DNS entry which is used to outline the servers that run a specific service for a domain name. In other words, you are able to use your domain not only for a website, but also for an instant messaging server, a video streaming host or even a Voice-Over-IP server, as an example, while you still have a website with it. Whenever you create the SRV record, you can select what Internet Protocol it's going to employ, 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 you have a number of SRV records for the exact same service. The second option will permit you to employ different machines for load balancing and redundancy. With this type of DNS records, you may use the same domain name many different purposes and even with different companies if the same one cannot provide all services you require.
