You can write RFCs, move them to STD status, and jump up and down all you want, but you can't stop domain name owners from creating "deep" sub-domains with deceptive names that make the important part of the name go off the end of the display area. > We > can use the UDRP and/or the legal system in various countries to > push back on those who register deceptive names and on the > registrars and registries that encourage the registration of > such names. The registrars and registries are not the problem. The domain name owners are. If a poor individual has created a deceptive name that hurts a huge company, that company may go after Microsoft (since it has deep pockets) instead of the poor person. So, the apps' current way of displaying the domain name (right-to-left) in left-to-right cultures is the problem. I tried to make the case that this is even a problem in the ASCII DNS (regardless of IDN), since hyphens are allowed in most DNS implementations. I wonder if a phisher would only have to change their own DNS server to get other characters (like ASCII slash '/') into the names? Or would many of the DNS clients refuse to lookup names containing such characters? (I tried to create a name containing ASCII slash yesterday, but my DNS server wouldn't accept it.) Hasn't this stuff been covered in any RFC yet? Erik
