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 an Internet site. This may be a Voice-Over-IP server, a video streaming service, an instant messaging system, and so on. When an SRV record is set up, you could specify an Internet Protocol that the domain name will use and the port, which is to be used to connect to the remote server. In addition, in case you have several SRV records for the very same service, you could set individual priorities and weights for each and every one of them, allowing you to distribute the load between several machines. Such a record will allow you to employ the same domain address or subdomains under it with different companies, so you can use it for different purposes even if you cannot get all services from just one service provider.
