An SRV record is a DNS record, which is used to redirect a domain name 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 many others. When an SRV record is set up, you can specify an Internet Protocol which the domain will use and the port, that will be employed to connect to the remote server. Additionally, in case you have numerous SRV records for the same service, you are able to set various priorities and weights for each and every one of them, so you can spread the load between several machines. Such a record allows you to employ the same domain or subdomains under it with different providers, so you can employ it for many purposes even if you can't get all of the services from a single provider.
