An SRV record is a DNS record, which is used to redirect a domain to a third-party server and employ it for a service different from an Internet site. This could be a Voice-Over-IP server, a video streaming service, an instant messaging system, etc. When an SRV record is set up, you are able to specify an Internet Protocol which the domain address will use and the port, which is to be employed to connect to the remote server. Also, if you have several SRV records for the same service, you'll be able to set individual priorities and weights for every one of them, so you can send out the load between a number of machines. Such a record will enable you to use the same domain or subdomains under it with different providers, so you can use it for different purposes even if you cannot get all of the services from a single service provider.
