An SRV record is a DNS record, which is used to redirect a domain name to a third-party server and employ it for some service different from an Internet site. 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 could specify an Internet Protocol which the domain will use and the port, which is to be employed to connect to the remote server. Furthermore, provided that you have a few SRV records for the exact same service, you can set different priorities and weights for each and every one of them, so you can distribute the load between several machines. Such a record will allow you to employ the same domain name or subdomains under it with different companies, so you're able to employ it for various purposes even if you are unable to get all of the services from just one service provider.
