An SRV record is a DNS record, that is used to forward a domain to a third-party server and use it for some service different from a 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 are able to specify an Internet Protocol which the domain name will use and the port, which will be used to connect to the remote server. Also, if you have numerous SRV records for the same service, you can set individual priorities and weights for every single one of them, allowing you to spread the load between a number of machines. Such a record will permit you to use the same domain name or subdomains under it with different providers, so you could employ it for various purposes even if you are not able to get all the services from one provider.
