An SRV record is a DNS record, that is used to point a domain to a third-party server and use it for a service different from a website. This could 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 which the domain will use and the port, which will be used to connect to the remote server. Also, if you have numerous SRV records for the very same service, you can set different priorities and weights for every one of them, so that you can send out the load between several machines. Such a record will permit you to use the same domain name or subdomains under it with different companies, so you can employ it for many purposes even if you are not able to get all of the services from a single service provider.
