An SRV record is a DNS record, that is used to forward a domain name to a third-party server and employ it for some service different from a website. This may be a Voice-Over-IP server, a video streaming service, an instant messaging system, etc. When an SRV record is created, you could specify an Internet Protocol the domain address will use and the port, which will be used to connect to the remote server. In addition, if you have many SRV records for the very same service, you can set various priorities and weights for each and every one of them, in order to distribute the load between several machines. Such a record will permit you to use the same domain name or subdomains under it with different providers, so you're able to employ it for different purposes even if you are not able to get all services from one service provider.
