An SRV record is a DNS record, that is used to redirect a domain to a third-party server and use it for some service different from an Internet 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 the domain address 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 same service, you are able to set various priorities and weights for each and every one of them, so you're able to distribute the load between many machines. Such a record will enable you to use the same domain address or subdomains under it with different companies, so you can employ it for various purposes even if you are not able to get all services from just one service provider.
