An SRV record is a DNS record, which is used to forward a domain name to a third-party server and employ it for some service different from a web site. This can be a Voice-Over-IP server, a video streaming service, an instant messaging system, and so on. When an SRV record is created, you could specify an Internet Protocol which the domain will use and the port, which is to be employed to connect to the remote server. Furthermore, in case you have a few SRV records for the exact same service, you'll be able to set different priorities and weights for every single one of them, so that you can distribute the load between many machines. Such a record will allow you to use the same domain address or subdomains under it with different companies, so you're able to use it for many purposes even if you cannot get all the services from a single provider.
