An SRV record is a DNS record, which is used to forward a domain name to a third-party server and use 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 created, you are able to specify an Internet Protocol which the domain name will use and the port, that will be employed to connect to the remote server. In addition, if you have a few SRV records for the very same service, you can set individual priorities and weights for each and every one of them, so you're able to distribute the load between several machines. Such a record allows you to use the same domain name or subdomains under it with different companies, so you could employ it for different purposes even if you cannot get all services from one provider.
