Hi osclass community.

In case you want to add IP Lookup on oc-admin listing page, this is what I did.

Folder = oc-admin\themes\omega\items\frm.php 
Line = 319

I replaced this part
                <div class="input-separate-top">
                  <label><?php ItemForm::show_email_checkbox(); ?><span><?php _e('Show e-mail'); ?></span></label>
                </div>
with this
                <div class="input-separate-top">
                  <label><?php ItemForm::show_email_checkbox(); ?><span><?php _e('Show e-mail'); ?></span></label>
<a href="http://ipinfo.io/<?php echo osc_item_ip(); ?>" target="_blank">Locate IP</a>
<a href="http://www.ip-tracker.org/locator/ip-lookup.php?ip=<?php echo osc_item_ip(); ?>" target="_blank">Locate IP</a>
                </div>

Enjoy! 

Thanks for feedback, will be added in Osclass 8.3
