An SRV record is a DNS record, that is used to redirect a domain to a third-party server and use it for some service different from a site. This may 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 address will use and the port, which is to be used to connect to the remote server. Furthermore, provided that you have numerous SRV records for the very same service, you can set individual priorities and weights for every one of them, so that you can distribute the load between several machines. Such a record will permit you to use the same domain or subdomains under it with different providers, so you could use it for different purposes even if you are not able to get all services from just one provider.
