An SRV record is a DNS record, that is used to redirect a domain name to a third-party server and employ it for a service different from a website. This could be a Voice-Over-IP server, a video streaming service, an instant messaging system, and many others. When an SRV record is created, you can specify an Internet Protocol that the domain will use and the port, which is to be used to connect to the remote server. Also, if you have a few SRV records for the exact same service, you can set various priorities and weights for each one of them, so that you can send out the load between a number of machines. Such a record will permit you to employ the same domain address or subdomains under it with different providers, so you can use it for many purposes even if you can't get all services from one provider.
