# This script expects the filename of the downloaded challenge image as its only parameter and will output the correct answer string.
# To prevent cheating, this version of the script has been modified in a few subtle ways so it will output an incorrect answer.

# Development process:
# - Use imagemagick to split input image into 40x40 px blocks

IPv6. You're doing it wrong.

If you're reading this, you've probably been called out on assigning unreasonably small IPv6 subnets or even individual IPv6 addresses to your customers.
Here's why you should reconsider and assign a separate /64 subnet to each customer:

• RFC 6177: IPv6 Address Assignment to End Sites:

  The recommendation in RFC 3177 to assign /48s as a default is not a requirement of the IPv6 architecture; anything of length /64 or shorter works from a standards perspective.
