An SRV record is a DNS record, which is used to forward a domain name to a third-party server and use it for some service different from a web 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 created, you are able to specify an Internet Protocol that the domain name will use and the port, which is to be employed to connect to the remote server. In addition, if you have numerous SRV records for the very same service, you are able to set individual priorities and weights for each one of them, so that you can distribute the load between many machines. Such a record will allow you to employ the same domain name or subdomains under it with different providers, so you're able to use it for many purposes even if you are unable to get all the services from one provider.
