This plugin adds an [whatsmyip] shortcode tag to WordPress. You can use it
to embed the current User’s IP address inline in a Post.
The shortcode takes 3 attributes, ip, country and coords. Each of
these can take boolean values like 1, yes, no, true. Truthy values
enable the display of the corresponding field.
For Eg:- To display ip and country details use,
[whatsmyip ip='yes' country='yes']
The ip attributes defaults to true if absent. Rest of the attributes
are false by default.
A Widget is also provided for use inside sidebars. Use the checkboxes in the Widget customization screen to change the displayed fields.
This plugin is available for download for your site.
