An SRV record is a DNS record, that is used to forward a domain name to a third-party server and use it for a service different from an Internet 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 set up, you are able to specify an Internet Protocol which the domain will use and the port, that will be used to connect to the remote server. Also, provided that you have many SRV records for the same service, you can set various priorities and weights for each and every one of them, so that you can distribute the load between several machines. Such a record allows you to use the same domain or subdomains under it with different providers, so you can employ it for many purposes even if you are not able to get all services from just one provider.
