HttpServletRequest.getRemoteAddr() in Tomcat returns IPv6 formatted IP address

Question

HttpServletRequest.getRemoteAddr() in Tomcat returns IPv6 formatted IP address, but I would like to configure it that returns IPv4.

I access the servlet via 'localhost'. If I access it via '127.0.0.1' then returns IPv4 formatted IP address (see this answer).

Environment:

• Windows 7 x64
• Tomcat 6.0.35-windows-x64

My LAN connection properties: IPv6 is checked off, but it doesn't work neither if I check it on.

Solution

try adding this parameter -Djava.net.preferIPv4Stack=true to your tomcat startup commandline.
