An SRV record is a DNS record, which is used to direct a domain name to a third-party server and employ it for some 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 could specify an Internet Protocol the domain address will use and the port, which is to be employed to connect to the remote server. Also, if you have many SRV records for the same service, you are able to set various priorities and weights for each one of them, so you can distribute the load between many machines. Such a record will allow you to employ the same domain or subdomains under it with different companies, so you can employ it for different purposes even if you can't get all of the services from one service provider.
