whats-my-ip

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.
