       I really like memory spy by @b0rk - here's an example that helped emphasize for me that IPv4 addresses really do fit in 4 bytes (I mean the clue is in the name, but still, this was a really neat demo)https://memory-spy.wizardzines.com/game.html#example=converting%20an%20IP%20address%20from%20a%20string

       @simon @b0rk It would be misleading to use the name IPv4 as a mnemonic for the size of the IP address. After all, an IPv6 address isn't 6 bytes. It's a version number.

       @simon @matt @b0rk it's still a reasonable mnemonic. IPv4 addresses always fit in 4 bytes, IPv6 deployment is always 6 years away

       @simon @b0rk @matt it also helps explain why many TV shows and films use IPs with a .280 or some other value >255 in them - they look real on screen but aren't valid so can't be visited by curious viewers who end up somewhere unexpected.
