An SRV record is a DNS record, that is used to redirect a domain to a third-party server and use 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 set up, you can specify an Internet Protocol which the domain will use and the port, that will be used to connect to the remote server. Moreover, provided that you have numerous 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 allow you to employ the same domain name or subdomains under it with different providers, so you can employ it for many purposes even if you are not able to get all the services from just one provider.
