An SRV record is a DNS record, which is used to point a domain to a third-party server and employ it for a service different from an Internet site. This can 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 name will use and the port, which will be used to connect to the remote server. Moreover, provided that you have a few SRV records for the very same service, you are able to set different priorities and weights for every one of them, allowing you to send out the load between several machines. Such a record will allow you to use the same domain address or subdomains under it with different providers, so you could use it for many purposes even if you can't get all the services from one service provider.
