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