An SRV record is a DNS record, which is used to point a domain name to a third-party server and use it for a service different from a website. This may 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 can specify an Internet Protocol that the domain will use and the port, which is to be used to connect to the remote server. In addition, if you have numerous SRV records for the very same service, you can set individual priorities and weights for each and every one of them, so that 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're able to use it for many purposes even if you are not able to get all services from one provider.
