Block Sites with the Hosts file

August 3rd, 2008

Hidden in the depths of the operating systems there lies a Hosts file. This Hosts file maps hostnames to IP addresses so can be used to redirect a website url and even block it.

Location of the Hosts file:

  • Windows NT/2000/XP/2003/Vista: %SystemRoot%\system32\drivers\etc\ is the default location, which may be changed. The actual directory is determined by the Registry key \HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\DataBasePath.
  • Windows 95/98/Me: %WinDir%\
  • Linux and other Unix-like operating systems: /etc
  • Mac OS 9 and earlier: System Folder: Preferences or System folder (format of the file may vary from Windows and Linux counterparts)
  • Mac OS X: /private/etc (uses BSD-style Hosts file)
  • OS/2 and eComStation: "bootdrive":\mptn\etc\
  • Symbian 1st/2nd edition phones: C:\system\data\hosts
  • Symbian 3rd edition phones: C:\private\10000882\hosts, only accessible with file browsers with AllFiles capability, most are not.
