An SRV record is a DNS record, that is used to direct a domain name to a third-party server and employ it for some service different from a 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 name will use and the port, which is to be employed to connect to the remote server. Also, provided that you have a few SRV records for the exact same service, you can set various priorities and weights for each and every one of them, in order to distribute the load between many machines. Such a record will allow you to use the same domain address or subdomains under it with different companies, so you can employ it for many purposes even if you are not able to get all services from one service provider.
