Hostname Lookup

By default, the Ipregistry API does not return the hostname a given IP address resolves to. The reason is that not everybody needs this information and returning a fresh hostname value requires to perform extra actions that slow down the response time.

In case you need it, append the API's hostname parameter and set it to true:
