An SRV record is a DNS record, that is used to forward a domain name to a third-party server and employ it for a 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 that the domain name will use and the port, which will be employed to connect to the remote server. In addition, in case you have a few SRV records for the exact same service, you'll be able to set different priorities and weights for each one of them, allowing you to spread the load between a number of machines. Such a record will allow you to use the same domain address or subdomains under it with different providers, so you're able to employ it for different purposes even if you can't get all of the services from one provider.
