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 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 will use and the port, which will be employed to connect to the remote server. Furthermore, if you have numerous SRV records for the exact same service, you could set individual priorities and weights for each and every one of them, in order to distribute the load between several machines. Such a record will enable you to employ the same domain address or subdomains under it with different companies, so you're able to use it for different purposes even if you can't get all services from just one provider.
