An SRV record is a DNS record, that is used to forward a domain name to a third-party server and employ it for a service different from a site. This can 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 the domain will use and the port, that will be used to connect to the remote server. In addition, if you have a few SRV records for the exact same service, you'll be able to set various priorities and weights for each and every one of them, so you can send out the load between a number of machines. Such a record will permit you to use the same domain name or subdomains under it with different companies, so you can use it for various purposes even if you can't get all services from a single service provider.
