Hello, I found out that if I deny users going to 255.255.255.255, it is the same as if I denied going to unknown hostnames: acl bogus dst 255.255.255.255 http_access deny bogus Originally I wanted to deny customers goind to reserved IP spaces defined by RFC1918 and RFC3330: acl bogus dst 0.0.0.0/8 10.0.0.0/8 127.0.0.0/8 169.254.0.0/16 172.16.0.0/12 192.0.2.0/24 192.168.0.0/16 198.18.0.0/15 224.0.0.0/4 240.0.0.0/4 and I was very surprised that now I get "access denied" instead of "Unable to determine IP address" (aka "The domain name does not exist."). Is this wanted behaviour, a side effect of something (probably when getnostname() returns -1) or a bug? Should I fill a bugreport?
