Step 1: edit /etc/apache2/ports.conf file
# If you just change the port or add more ports here, you will likely also
# have to change the VirtualHost statement in
# /etc/apache2/sites-enabled/000-default
# This is also true if you have upgraded from before 2.2.9-3 (i.e. from
# Debian etch). See /usr/share/doc/apache2.2-common/NEWS.Debian.gz and
# README.Debian.gz
#NameVirtualHost *:80
#Listen 80
NameVirtualHost 176.31.75.56:80
Listen 176.31.75.56:80
NameVirtualHost [2001:41d0:a:3171:0:1041:2729:a652]:80
Listen [2001:41d0:a:3171:0:1041:2729:a652]:80
<IfModule mod_ssl.c>
# If you add NameVirtualHost *:443 here, you will also have to change
# the VirtualHost statement in /etc/apache2/sites-available/default-ssl
# to <VirtualHost *:443>
# Server Name Indication for SSL named virtual hosts is currently not
# supported by MSIE on Windows XP.
Listen 443
