An SRV record is a DNS record, which is used to direct a domain to a third-party server and use it for a service different from a site. 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 address will use and the port, which will be used to connect to the remote server. Furthermore, if you have numerous SRV records for the same service, you can set individual priorities and weights for each and every one of them, so you're able to spread the load between many machines. Such a record will permit you to employ the same domain address or subdomains under it with different companies, so you're able to use it for many purposes even if you are not able to get all of the services from a single service provider.
