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:
My LAN connection properties:
IPv6 is checked off, but it doesn’t work neither if I check it on.
try adding this parameter
-Djava.net.preferIPv4Stack=trueto your tomcat startup commandline.
