An SRV record is a DNS record, that is used to forward a domain name to a third-party server and use it for some service different from a website. This could be a Voice-Over-IP server, a video streaming service, an instant messaging system, and so forth. When an SRV record is created, you can specify an Internet Protocol that the domain address will use and the port, which is to be used to connect to the remote server. Moreover, in case you have several SRV records for the very same service, you could set different priorities and weights for each one of them, allowing you to spread the load between several machines. Such a record will permit you to use the same domain name or subdomains under it with different companies, so you could use it for various purposes even if you are unable to get all of the services from a single service provider.
