An SRV record is a DNS record, that is used to direct a domain to a third-party server and employ it for a service different from an Internet site. This can be a Voice-Over-IP server, a video streaming service, an instant messaging system, and many others. When an SRV record is set up, you are able to specify an Internet Protocol which the domain will use and the port, that will be used to connect to the remote server. In addition, if you have numerous SRV records for the very same service, you are able to set different priorities and weights for every single one of them, so you can spread the load between several machines. Such a record will allow you to use the same domain address or subdomains under it with different providers, so you could use it for different purposes even if you are not able to get all of the services from one provider.
