This plugin hasn’t been tested with the latest 3 major releases of WordPress. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress.



This plugin provides detailed info about an IPv4 or IPv6 subnet.

How do you use it? Place the IP adres and CIDR subnet between [subnetinfo] and [/subnetinfo] brackets.

Use the following format : [subnetinfo]FE80:0000:0000:0000:0202:B3FF:FE1E:8329/64[/subnetinfo]

or [subnetinfo][/subnetinfo]

It will be automatically parsed to a nice layout.

The address identification and all calculation are carried out within the plugin itself.

A link to IANA is created in the results to the corresponding RFC which describes more details about the specific IP range.
For some special IP ranges that are not directly described in an RFC, a link to a relevant website or Wikipedia site is offered.
