An SRV record is a DNS record, which is used to redirect a domain name to a third-party server and employ it for a service different from a 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 set up, you are able to specify an Internet Protocol that the domain address will use and the port, that will be employed to connect to the remote server. Additionally, in case you have a few SRV records for the exact same service, you'll be able to set different priorities and weights for every single one of them, so you can send out the load between many machines. Such a record allows you to use the same domain address or subdomains under it with different providers, so you could employ it for many purposes even if you are unable to get all of the services from just one provider.
