An SRV record is a DNS record, which is used to point a domain to a third-party server and employ it for some 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 created, you could specify an Internet Protocol the domain name will use and the port, which will be used to connect to the remote server. Additionally, if you have numerous SRV records for the very same service, you can set individual priorities and weights for every one of them, allowing you to send out the load between a number of machines. Such a record allows you to employ the same domain or subdomains under it with different providers, so you can employ it for various purposes even if you are unable to get all of the services from a single service provider.
