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 an Internet site. This could be a Voice-Over-IP server, a video streaming service, an instant messaging system, and so on. When an SRV record is set up, you are able to specify an Internet Protocol that the domain address will use and the port, which is to be employed to connect to the remote server. In addition, if you have several SRV records for the same service, you are able to set various priorities and weights for each and every one of them, allowing you to distribute the load between a number of machines. Such a record will enable you to use 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 of the services from one provider.
