An SRV record is a DNS record, that is used to forward a domain name to a third-party server and employ it for a service different from a site. This could be a Voice-Over-IP server, a video streaming service, an instant messaging system, and so forth. When an SRV record is created, you are able to specify an Internet Protocol that the domain will use and the port, which will be used to connect to the remote server. In addition, if you have several SRV records for the very same service, you can set individual priorities and weights for each one of them, in order to distribute the load between several machines. Such a record allows you to use the same domain or subdomains under it with different companies, so you're able to employ it for many purposes even if you cannot get all of the services from just one provider.
