An SRV record is a DNS record, which is used to direct a domain name to a third-party server and use it for a service different from a web 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 that 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 each one of them, in order to send out the load between several machines. Such a record will permit you to use the same domain address or subdomains under it with different providers, so you could use it for various purposes even if you cannot get all the services from just one service provider.
