An SRV record is a DNS record, which is used to forward a domain to a third-party server and use it for a service different from a web site. This can be a Voice-Over-IP server, a video streaming service, an instant messaging system, etc. When an SRV record is set up, you are able to specify an Internet Protocol that the domain will use and the port, which will be used to connect to the remote server. In addition, 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, allowing you to distribute the load between a number of machines. Such a record will allow you to use the same domain address or subdomains under it with different companies, so you could employ it for many purposes even if you are not able to get all the services from a single service provider.
