`  == User warnings for IP 220.245.178.137 ==  Just thought I should inform you that this IP address is an ISP proxy server in Australia, there are several ban warnings posted under ``User Talk`` for it. The ISP does give each user a directly internet addressable IP but they are dynamically allocated (IP is DHCP assigned at login, however the subnet does remain the same for a given user as far as I can tell. If possible you may want to switch to x.x.x.0/24 subnet bans behind the proxy using HTTP_FORWARDED_FOR_X to get the range).`
