An SRV record is a DNS record, that is used to forward a domain to a third-party server and use 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, etc. When an SRV record is set up, you are able to specify an Internet Protocol that the domain address will use and the port, which will be employed to connect to the remote server. Additionally, in case you have many SRV records for the very same service, you are able to set different priorities and weights for every one of them, in order to distribute the load between a number of machines. Such a record allows you to use the same domain name or subdomains under it with different companies, so you're able to employ it for many purposes even if you cannot get all services from just one provider.
