An SRV record is a DNS record, that is used to forward a domain name to a third-party server and use it for a service different from a site. This could 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, which is to be employed to connect to the remote server. Additionally, in case you have numerous SRV records for the very same service, you could set different priorities and weights for each one of them, in order to spread the load between several machines. Such a record will permit you to employ the same domain name or subdomains under it with different providers, so you could use it for many purposes even if you cannot get all services from just one provider.
