An SRV record is a DNS record, that is used to point a domain name to a third-party server and employ it for some service different from a website. This could 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 that the domain address will use and the port, that will be used to connect to the remote server. Additionally, if you have a few SRV records for the very same service, you could set individual priorities and weights for each one of them, so you can send out the load between many machines. Such a record will allow you to use the same domain address or subdomains under it with different companies, so you can employ it for different purposes even if you are unable to get all the services from one provider.
