- TweedHeads 17y agoI was wondering if there is a specific barcode for IPv6 so we can tag the world and scan it with our mobile phones, wherever we are. Yes, there are many barcodes that can be used for that purpose, but I mean, can we hackers design a simple and specific barcode for IPv6? Circled, squared, linear? Bitcode, hexcode? Emphasis: simple and specific. Should we open an HN contest? Reward: world recognition for a thousand years.
