An SRV record is a DNS record, that is used to redirect a domain to a third-party server and employ 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 set up, you could specify an Internet Protocol the domain will use and the port, which will be employed to connect to the remote server. In addition, if you have many SRV records for the very same service, you could set individual priorities and weights for every one of them, so you're able to send out the load between a number of machines. Such a record will enable you to use the same domain or subdomains under it with different companies, so you can employ it for many purposes even if you are unable to get all the services from just one provider.
