An SRV record is a DNS record, which is used to direct a domain to a third-party server and use it for a service different from a 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 set up, you can specify an Internet Protocol the domain will use and the port, which is to be employed to connect to the remote server. Also, provided that you have many SRV records for the same service, you can set individual priorities and weights for each one of them, in order to distribute the load between a number of machines. Such a record allows you to employ the same domain or subdomains under it with different companies, so you can employ it for many purposes even if you cannot get all of the services from one provider.
