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 website. This may be a Voice-Over-IP server, a video streaming service, an instant messaging system, and so on. When an SRV record is set up, you could specify an Internet Protocol the domain name will use and the port, which will be used to connect to the remote server. Furthermore, in case you have numerous SRV records for the same service, you can set different priorities and weights for every one of them, so you can send out the load between many machines. Such a record will permit you to employ the same domain or subdomains under it with different companies, so you can employ it for many purposes even if you can't get all services from a single provider.
