An SRV record is a DNS record, that is used to redirect a domain name to a third-party server and employ it for some service different from a website. This may be a Voice-Over-IP server, a video streaming service, an instant messaging system, and so on. When an SRV record is set up, you are able to specify an Internet Protocol 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 same service, you are able to set different priorities and weights for every single one of them, so you're able to spread the load between several machines. Such a record will enable you to employ the same domain name or subdomains under it with different providers, so you could use it for various purposes even if you are unable to get all services from one service provider.
