An SRV record is a DNS record, that is used to forward a domain name to a third-party server and use it for a service different from a website. This may be a Voice-Over-IP server, a video streaming service, an instant messaging system, and so forth. When an SRV record is set up, you could specify an Internet Protocol which the domain name will use and the port, which will be employed to connect to the remote server. Also, if you have many SRV records for the very same service, you can set various priorities and weights for every single one of them, allowing you to send out the load between several machines. Such a record will allow you to employ the same domain address or subdomains under it with different companies, so you're able to employ it for many purposes even if you can't get all the services from a single service provider.
