An SRV record is a DNS record, that is used to redirect a domain to a third-party server and employ it for a service different from a site. This may be a Voice-Over-IP server, a video streaming service, an instant messaging system, and so forth. When an SRV record is set up, you can specify an Internet Protocol which the domain address will use and the port, that will be used to connect to the remote server. In addition, provided that you have numerous SRV records for the very same service, you can set various priorities and weights for every one of them, in order to distribute the load between many machines. Such a record will permit you to employ the same domain or subdomains under it with different providers, so you could employ it for many purposes even if you are unable to get all of the services from just one provider.
