An SRV record is a DNS record, which is used to redirect a domain name to a third-party server and use it for a service different from a website. This can 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 is to be used to connect to the remote server. In addition, if you have several SRV records for the same service, you could set different priorities and weights for each one of them, allowing you to spread the load between a number of machines. Such a record will allow you to use the same domain or subdomains under it with different providers, so you're able to employ it for various purposes even if you cannot get all services from a single provider.
