An SRV record is a DNS record, that is used to forward a domain name to a third-party server and use it for a service different from an Internet site. 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 can specify an Internet Protocol that the domain will use and the port, which is to be employed to connect to the remote server. Moreover, in case you have a few SRV records for the very same service, you can set different priorities and weights for each and every one of them, so you're able to distribute the load between many machines. Such a record allows you to employ the same domain or subdomains under it with different companies, so you can employ it for various purposes even if you can't get all of the services from just one service provider.
