title: IP database from ip2location and convert IPV4 to IPV6 in Perl
body: <p>I am trying to use IP to country database from <a href="http://www.ip2location.com/file-download" rel="nofollow">ip2location</a>.</p>
  
  <p>My question is, does the IPV6 database files already contains the IPV4 address embedded
  or do I have to use both IPV4 and IPV6 databases to cover all the IP Ranges for the internet
  for all versions.</p>
  
  <p>What I mean if I want to support both IPV4 and IPV6 I should load both database files
  into the same mysql table or should I just use IPV6.</p>
  
  <p>I am talking about the file IP2LOCATION-LITE-DB11.CSV.ZIP and IP2LOCATION-LITE-DB11.IPV6.CSV.ZIP</p>
