An SRV record is a DNS record, which is used to direct a domain name to a third-party server and use it for a service different from a website. This could be a Voice-Over-IP server, a video streaming service, an instant messaging system, and many others. When an SRV record is created, you can specify an Internet Protocol which the domain will use and the port, which is to be employed to connect to the remote server. Moreover, if you have several SRV records for the same service, you could set individual priorities and weights for every one of them, so you're able to send out the load between many machines. Such a record will enable you to use the same domain address or subdomains under it with different providers, so you're able to employ it for many purposes even if you cannot get all the services from a single service provider.
