A hex upon you
Posted by aogWednesday, 02 April 2008 at 13:28 TrackBack Ping URL

I got some junk email today trying to trick me out of financial data by claiming to be from the IRS with a tax refund for me. What makes this funny is that the URL to click to get my “refund” is

http://0xCA.0x27.0x30.0xDD/blah-IRS-looking-name-blah

The URL works, which actually surprised me. I realized that it was just an IP address encoded in hexadecimal (that’s what the “0x” means to most computers and code geeks) but I didn’t think that most browsers would bother to parse it. I suppose it’s an effort to get around sending the target to a bogus website without being obvious about it, which would mean that that junker thinks most people will recognize “normal” looking IP addresses (such as 172.16.177.34) and decided that hexadecimal would fool more people.

172.16.177.34 can also be represented as a purely decimal address, http://2886775074.
