Webserver Apache2 (httpd2)

17.3. Webserver Apache2 (httpd2)

Apache web server supports IPv6 native by maintainers since 2.0.14. Available patches for the older 1.3.x series are not current and shouldn't be used in public environment, but available at KAME / Misc.

17.3.1. Listening on IPv6 addresses

Note: virtual hosts on IPv6 addresses are broken in versions until 2.0.28 (a patch is available for 2.0.28).

17.3.1.1. Virtual host listen on an IPv6 address only

Listen [3ffe:ffff:100::1]:80
<VirtualHost [3ffe:ffff:100::1]:80>
        ServerName ipv6only.yourdomain.yourtopleveldomain
        # ...sure more config lines
</VirtualHost>
    

17.3.1.2. Virtual host listen on an IPv6 and on an IPv4 address

Listen [3ffe:ffff:100::2]:80 
Listen 1.2.3.4:80
<VirtualHost [3ffe:ffff:100::2]:80 1.2.3.4:80>
        ServerName ipv6andipv4.yourdomain.yourtopleveldomain
        # ...sure more config lines
</VirtualHost>
    

This should result after restart in e.g.

# netstat -lnptu |grep "httpd2\W*$" 
tcp 0 0 1.2.3.4:80          0.0.0.0:* LISTEN 12345/httpd2 
tcp 0 0 3ffe:ffff:100::1:80 :::*      LISTEN 12345/httpd2 
tcp 0 0 3ffe:ffff:100::2:80 :::*      LISTEN 12345/httpd2
    

For simple tests use the telnet example already shown.
