An SRV record is a DNS record, that is used to forward a domain name to a third-party server and employ it for some 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 set up, you could specify an Internet Protocol that the domain will use and the port, which is to be used to connect to the remote server. Furthermore, if you have numerous SRV records for the very same service, you could set various priorities and weights for every one of them, allowing you to distribute the load between several machines. Such a record will allow you to employ the same domain address or subdomains under it with different providers, so you can employ it for various purposes even if you can't get all of the services from just one service provider.
