An SRV record is a DNS record, which is used to forward 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 could specify an Internet Protocol the domain will use and the port, which is to be employed to connect to the remote server. Also, if you have a few SRV records for the same service, you could set various priorities and weights for each and every one of them, in order to send out the load between several machines. Such a record will enable you to use the same domain address or subdomains under it with different providers, so you could use it for many purposes even if you are unable to get all of the services from just one service provider.
