An SRV record is a DNS record, which is used to forward a domain name to a third-party server and employ it for a service different from a web site. This could be a Voice-Over-IP server, a video streaming service, an instant messaging system, and so on. When an SRV record is created, you can specify an Internet Protocol that the domain address will use and the port, which will be employed to connect to the remote server. In addition, in case you have many SRV records for the very same service, you are able to set various priorities and weights for each one of them, so you're able to send out the load between several machines. Such a record will enable you to use the same domain name or subdomains under it with different providers, so you could use it for various purposes even if you cannot get all services from a single service provider.
