Quiza al guien sabe como configurar dominios virtuales sin utilizar la ip 127.0.0.1 sino por ejemplo 192.168.1.4 o la q sea modificando el archivo c:\windows\system32\drivers\etc\hosts y los archivos de apache httpd.conf y httpd-vhosts.conf.

Aqui esta lo que hice

En el archivo hosts

# Copyright (c) 1993-2009 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

# localhost name resolution is handled within DNS itself.
# 127.0.0.1 localhost
# ::1 localhost
192.168.1.4 www.mipagina.com

en el archivo httpd.conf quite # y deje así:
# Virtual hosts
Include conf/extra/httpd-vhosts.conf

---------------------------------------------------------------------------------------------
en el archivo httpd-vhosts.conf:

#
# Virtual Hosts
#
# If you want to maintain multiple domains/hostnames on your
# machine you can setup VirtualHost containers for them. Most configurations
# use only name-based virtual hosts so the server doesn't need to worry about
# IP addresses. This is indicated by the asterisks in the directives below.
#
# Please see the documentation at
# <URL:http://httpd.apache.org/docs/2.2/vhosts/>
# for further details before you try to setup virtual hosts.
#
# You may use the command line option '-S' to verify your virtual host
# configuration.

#
# Use name-based virtual hosting.
#
NameVirtualHost 192.168.1.4:80

#
# VirtualHost example:
# Almost any Apache directive may go into a VirtualHost container.
# The first VirtualHost section is used for all requests that do not
# match a ServerName or ServerAlias in any <VirtualHost> block.
#
#<VirtualHost *:80>
# ServerAdmin [email protected]
# DocumentRoot "C:/Program Files/Apache Software Foundation/Apache2.2/docs/dummy-host.localhost"
# ServerName dummy-host.localhost
# ServerAlias www.dummy-host.localhost
# ErrorLog "logs/dummy-host.localhost-error.log"
# CustomLog "logs/dummy-host.localhost-access.log" common
#</VirtualHost>

#<VirtualHost *:80>
# ServerAdmin [email protected]
# DocumentRoot "C:/Program Files/Apache Software Foundation/Apache2.2/docs/dummy-host2.localhost"
# ServerName dummy-host2.localhost
# ErrorLog "logs/dummy-host2.localhost-error.log"
# CustomLog "logs/dummy-host2.localhost-access.log" common
#</VirtualHost>

<VirtualHost 192.168.1.4:80>
DocumentRoot "c:/wamp/www/paginas"
ServerName www.mipagina.com
</VirtualHost>

Esto si funciona trabajando con 127.0.0.1 pero al trabajar con otras ip ya no.
