Machine Name=System

I hosted following 3 websites on my system:

1) ---- ---- Main Website

2) ---- ---- Test Site

3) ---- ---- Test Site

when i putted Domain Name of all above mentioned sites in browser, these sites was opened.

But when i putted IPs in browser (, 0.2, 0.3), it opened the page of
(Main Site) thats hosted on

Nslookup & Dig command also showed true results.

I cant undestand its a DNS or Apache Problem
