An SRV record is a DNS record, that is used to forward a domain to a third-party server and use it for a service different from an Internet site. This could be a Voice-Over-IP server, a video streaming service, an instant messaging system, and so on. When an SRV record is created, you are able to specify an Internet Protocol the domain name will use and the port, which will be used to connect to the remote server. Additionally, in case you have several SRV records for the very same service, you can set different priorities and weights for each one of them, so you can send out 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 employ it for different purposes even if you are unable to get all of the services from one provider.
