An SRV record is a DNS record, that is used to direct a domain name to a third-party server and use it for some service different from a website. This could be a Voice-Over-IP server, a video streaming service, an instant messaging system, and many others. When an SRV record is set up, you can specify an Internet Protocol which the domain will use and the port, which will be used to connect to the remote server. Furthermore, provided that you have numerous SRV records for the exact same service, you can set various priorities and weights for each and every one of them, so that you can spread the load between several machines. Such a record will permit you to employ the same domain address or subdomains under it with different companies, so you can employ it for many purposes even if you are unable to get all the services from a single provider.
