An SRV record is a DNS record, that is used to redirect a domain to a third-party server and use 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 forth. When an SRV record is set up, you could specify an Internet Protocol the domain address 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 very same service, you can set various priorities and weights for each and every one of them, allowing you to send out the load between several machines. Such a record will allow you to use the same domain name or subdomains under it with different companies, so you can employ it for various purposes even if you are unable to get all the services from one provider.
