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 web 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 set up, you can specify an Internet Protocol the domain address will use and the port, that will be employed to connect to the remote server. Furthermore, if you have numerous 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 several machines. Such a record will allow you to use the same domain or subdomains under it with different providers, so you could employ it for many purposes even if you can't get all of the services from just one provider.
