An SRV record is a DNS record, that is used to forward 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 so on. When an SRV record is created, you could specify an Internet Protocol that the domain will use and the port, that will be used to connect to the remote server. Additionally, in case you have numerous SRV records for the very same service, you can set individual priorities and weights for each and every one of them, so you can distribute the load between several machines. Such a record will permit you to employ the same domain address or subdomains under it with different providers, so you can employ it for many purposes even if you can't get all the services from just one provider.
