An SRV record is a DNS record, which is used to direct a domain to a third-party server and employ it for some service different from a site. This can be a Voice-Over-IP server, a video streaming service, an instant messaging system, and so on. When an SRV record is created, you are able to specify an Internet Protocol which the domain address will use and the port, which is to be employed to connect to the remote server. Furthermore, in case you have a few SRV records for the same service, you can set individual priorities and weights for each and every one of them, so you can distribute the load between a number of machines. Such a record will enable you to use the same domain address or subdomains under it with different companies, so you can employ it for various purposes even if you are unable to get all the services from one service provider.
