An SRV record is a DNS record, which is used to redirect a domain name to a third-party server and employ it for a service different from a website. This can 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 that the domain name will use and the port, that will be used to connect to the remote server. Additionally, in case you have numerous SRV records for the exact same service, you can set individual priorities and weights for every single one of them, in order to send out the load between several machines. Such a record will allow you to employ the same domain or subdomains under it with different providers, so you could employ it for different purposes even if you cannot get all of the services from a single provider.
