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 website. This could 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 are able to specify an Internet Protocol which the domain address will use and the port, which will be employed to connect to the remote server. Moreover, if you have many SRV records for the exact same service, you could set individual priorities and weights for every one of them, so that you can distribute the load between a number of machines. Such a record will permit you to use the same domain or subdomains under it with different providers, so you can employ it for various purposes even if you cannot get all the services from just one service provider.
