An SRV record is a DNS record, that is used to forward a domain to a third-party server and employ it for some service different from an Internet site. This may be a Voice-Over-IP server, a video streaming service, an instant messaging system, and so forth. When an SRV record is created, you can specify an Internet Protocol which the domain name will use and the port, which will be employed to connect to the remote server. Moreover, in case you have several SRV records for the same service, you can set different priorities and weights for every single one of them, allowing you to send out the load between many machines. Such a record will allow you to use the same domain or subdomains under it with different providers, so you can use it for different purposes even if you cannot get all the services from just one service provider.
