Проблема с изменением hosts

[_-Re@l-_]

Вот такой стандратно hosts:
# Copyright (c) 1993-2006 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host

127.0.0.1 localhost

А я хочу сделать так:

127.0.0.1 www.yandex.ru
Однако, я всё равно могу заходить на Яндекс. Почему?

[coirius]

может потому, что вы набираете yandex.ru а не www.yandex.ru?

[_-Re@l-_]

Не, я правильно набираю, однако всё равно заходит.

[grafgrial]

странно у меня тоже

Так как правильно блокировать сайты?

127.0.0.1 www.yandex.ru
127.0.0.1 yandex.ru
