An SRV record is a DNS record, which is used to point a domain name to a third-party server and employ it for a service different from an Internet 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 created, you are able to specify an Internet Protocol the domain name will use and the port, that will be used to connect to the remote server. Also, if you have numerous SRV records for the very same service, you can set individual priorities and weights for each one of them, so you're able to send out the load between several machines. Such a record will allow you to use the same domain or subdomains under it with different companies, so you're able to use it for different purposes even if you are not able to get all services from one service provider.
