An SRV record is a DNS record, that is used to forward a domain to a third-party server and employ it for a service different from a 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 name will use and the port, which is to be used to connect to the remote server. Also, if you have many SRV records for the exact same service, you'll be able to set different priorities and weights for every single one of them, so you can send out the load between a number of machines. Such a record will enable you to employ the same domain or subdomains under it with different providers, so you can use it for various purposes even if you are unable to get all services from one service provider.
