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 web site. This could be a Voice-Over-IP server, a video streaming service, an instant messaging system, and so on. When an SRV record is set up, you could specify an Internet Protocol the domain address will use and the port, which will be employed to connect to the remote server. Additionally, provided that you have a few SRV records for the exact same service, you are able to set individual priorities and weights for every one of them, so you can spread the load between many machines. Such a record will permit you to employ the same domain or subdomains under it with different providers, so you can employ it for various purposes even if you can't get all of the services from a single provider.
