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 created, 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, if you have many SRV records for the same service, you are able to set different priorities and weights for each one of them, in order to send out the load between several machines. Such a record allows you to employ the same domain address or subdomains under it with different providers, so you can use it for many purposes even if you are not able to get all the services from one provider.
