An SRV record is a DNS record, which is used to point a domain name to a third-party server and employ it for some 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 which the domain name will use and the port, which is to be employed to connect to the remote server. Additionally, if you have several SRV records for the very same service, you could set different priorities and weights for every single one of them, so that you can spread the load between many machines. Such a record allows you to use the same domain address or subdomains under it with different companies, so you could employ it for different purposes even if you cannot get all services from one service provider.
