An SRV record is a DNS record, that is used to point a domain name to a third-party server and use it for a service different from a website. This could be a Voice-Over-IP server, a video streaming service, an instant messaging system, etc. 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 used to connect to the remote server. In addition, provided that you have many SRV records for the same service, you are able to set different priorities and weights for each one of them, allowing you to spread the load between a number of machines. Such a record will allow you to use the same domain address or subdomains under it with different companies, so you can employ it for many purposes even if you are not able to get all services from one service provider.
