Hallo everybody, mod_remoteip does not support the IPv6 address notation with the address within brackets: [2a02:2e0:40c:ffff::3]:80 The above mentioned format is being used for example by KEMP loadbalancers within the Via / X-Forwarded-For header. Using this format leads to ips like 127.0.0.6 in the logs. I also described this issue in a bit more detail within: http://stackoverflow.com/questions/39237887/x-forwarded-for-127-0-0-6-when-using-ipv6/40310893#40310893 Best regards, Matthias
