An SRV record is a DNS record, that is used to direct a domain to a third-party server and use it for a 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 set up, you can specify an Internet Protocol which the domain address will use and the port, which is to be employed to connect to the remote server. In addition, provided that you have a few SRV records for the exact same service, you'll be able to set various priorities and weights for each one of them, so you can distribute the load between many machines. Such a record will allow you to employ the same domain or subdomains under it with different companies, so you could employ it for many purposes even if you cannot get all of the services from a single provider.
