An SRV record is a DNS record, which is used to point a domain to a third-party server and use it for a service different from a web site. This may be a Voice-Over-IP server, a video streaming service, an instant messaging system, and so forth. When an SRV record is set up, you can specify an Internet Protocol the domain will use and the port, that will be used to connect to the remote server. In addition, in case you have many SRV records for the same service, you are able to set individual priorities and weights for every one of them, so you can distribute the load between a number of machines. Such a record will enable you to use the same domain name or subdomains under it with different providers, so you're able to use it for different purposes even if you are not able to get all services from just one provider.
