An SRV record is a DNS record, which is used to forward a domain name to a third-party server and employ it for a service different from an Internet site. 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 the domain name will use and the port, which is to be used to connect to the remote server. Moreover, provided that you have a few SRV records for the very same service, you can set different priorities and weights for each and every one of them, so you're able to distribute the load between several machines. Such a record allows you to use the same domain address or subdomains under it with different companies, so you could use it for various purposes even if you are unable to get all the services from one service provider.
