title: IP Address gets redirected to Sub-domain instead of Domain
body: <p>I have a domain lets consider example.com and sub-domain blog.example.com
  Both running in the same VPS with a static IP served by Nginx, both listening at port 80.</p>
  
  <p>Before adding my sub-domain whenever I entered my IP Address in the browser, the default domain was served (i.e example.com). But after adding blog subdomain, entering IP address redirect to blog.example.com instead. How can I redirect it to example.com by default? Can using a different port number for blog.example.com could solve this?</p>
