An SRV record is a DNS record, which is used to direct a domain name 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 on. When an SRV record is set up, you could specify an Internet Protocol that the domain name will use and the port, which is to be used to connect to the remote server. In addition, in case you have many SRV records for the same service, you are able to set individual priorities and weights for each one of them, in order to send out the load between several machines. Such a record will enable you to use the same domain address or subdomains under it with different providers, so you can employ it for various purposes even if you can't get all services from just one service provider.
