An SRV record is a DNS record, that is used to redirect a domain name to a third-party server and employ it for a service different from a website. This could be a Voice-Over-IP server, a video streaming service, an instant messaging system, and so on. When an SRV record is set up, you are able to specify an Internet Protocol the domain name will use and the port, which will be used to connect to the remote server. Also, in case you have numerous SRV records for the very same service, you'll be able to set different priorities and weights for every one of them, so you can send out the load between many machines. Such a record will enable you to use the same domain name or subdomains under it with different companies, so you can use it for various purposes even if you can't get all of the services from one service provider.
