Ashwani, The ensure your Apache has or does not have IPv6 support you can check the build parameters of httpd by running httpd.exe -V. If your Apache has IPv6 support you should see: -D APR_HAVE_IPV6 (IPv4-mapped addresses disabled). If that parameter isn't present then your Apache doesn't have IPv6 support Given you tested with an IPv6 stack and received a startup error (guessing a socket error) it's probably safe to say your Apache doesn't support it. Last I checked Apache 2.2.4 (going by your email to the dev list) on Windows needs to be compiled with IPv6 support. To build with IPv6 support edit apache_src\srclib\apr\include\apr.hw and enable #define APR_HAVE_IPV6 0.
