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