I'm having an issue in that using just the IP address (or subnet) in the proxy exceptions (Tools, Internet Options, Connections, LAN Settings) does not appear to work.
I've added the specific IP address, AND subnet but the traffic still goes to the proxy when I use the FQDN http://site.com instead. It's fine when I use the IP address in the address bar OR the site name in the exceptions.
The problem is that the full site name is huge and I'm concerned about the 255 character limit being hit too quickly. I am aware of the hack to up it to 1000 characters but I'm also aware of the performance hit this entails.
Could someone confirm for me that you MUST use the exact / wildcard of the address used in the address bar, and can't just put in the IP address?
I know it is not name resolution as I have put the site IP address in the HOSTS file and ensured that the correct IP is used.
