not getting zip code corresponding to given ip address

[dinesh1985singh]

Hi all,

I want to get the zip code from an ip address of the client machine.I am using http://ipinfodb.com api to get my task done. I am getting almost every thing except zip code,Gmt offset,and timezone.
You can check it here :http://api.ipinfodb.com/v2/ip_query.php?key=7e3d3f24491b21b01d91fbeddd6954c4bd917189e546717b5bf8e5f05ab67eeb&ip=121.245.223.73&timezone=true

on this url I am getting every thing done

But on implementing the same thing on my testing site :
http://dev.bottlenotes.com/ipinfoDb.php

Info db provide his own class .

Please help me out in this regard or you can give me an alternative link from where I can get my task done .

I am basically looking for a free ip to zip code look up service.

Thanks .
