An SRV record is a DNS record, that is used to redirect a domain name to a third-party server and employ it for a service different from a site. This may be a Voice-Over-IP server, a video streaming service, an instant messaging system, and many others. When an SRV record is created, you are able to specify an Internet Protocol the domain will use and the port, that will be used to connect to the remote server. Furthermore, if you have a few SRV records for the same service, you'll be able to set individual priorities and weights for each and every one of them, in order to distribute the load between many machines. Such a record will enable you to employ the same domain address or subdomains under it with different companies, so you're able to employ it for various purposes even if you cannot get all the services from just one service provider.
