An SRV record is a DNS record, that is used to direct a domain to a third-party server and use it for a service different from a site. This may be a Voice-Over-IP server, a video streaming service, an instant messaging system, etc. When an SRV record is created, you could specify an Internet Protocol which the domain will use and the port, that will be employed to connect to the remote server. Additionally, provided that you have a few SRV records for the exact same service, you can set various priorities and weights for each and every one of them, allowing you to send out the load between a number of machines. Such a record allows you to use the same domain address or subdomains under it with different providers, so you can employ it for different purposes even if you are not able to get all of the services from just one service provider.
