An SRV record is a DNS record, which is used to forward a domain to a third-party server and use it for a service different from a site. This may be a Voice-Over-IP server, a video streaming service, an instant messaging system, and so on. When an SRV record is created, you are able to specify an Internet Protocol the domain name will use and the port, which is to be employed to connect to the remote server. Moreover, in case you have numerous SRV records for the same service, you are able to set individual priorities and weights for every one of them, so you're able to distribute the load between a number of machines. Such a record will permit you to use the same domain name or subdomains under it with different providers, so you can employ it for many purposes even if you are unable to get all of the services from one provider.
