An SRV record is a DNS record, which is used to redirect a domain name to a third-party server and employ 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 on. When an SRV record is created, you are able to specify an Internet Protocol which the domain address will use and the port, which is to be used to connect to the remote server. In addition, in case you have numerous SRV records for the exact same service, you could set various priorities and weights for every single one of them, so you can send out the load between many machines. Such a record will allow you to use the same domain name or subdomains under it with different providers, so you're able to employ it for different purposes even if you are unable to get all the services from just one service provider.
