The move to hex is to avoid people having to memorise all these offhands like "so a /27 is x.x.x.0-31". Instead every "4" in the subnet is another digit. But a

  Maybe I'm weird, but I do in fact think that is easier. People memorize long numbers all the time, such as SSN, phone numbers, account numbers, credit card numbers, etc. People are not very good at memorizing lengthy alphanumeric sequences such as randomized passwords. I don't know why, but it "just is". But - > The move to hex is to avoid people having to memorise all these offhands Point taken. It does seem in practice though people will still have a need to memorize/recognize addresses for various purposes, such as administration/dns/etc.

    > People memorize long numbers all the time, such as SSN, phone numbers, account numbers, credit card numbers, etc. People are not very good at memorizing lengthy alphanumeric sequences such as randomized passwords. It's easy. Long sequence of 10 possible tokens that we're always used to seeing together. Easier to memorize because you subconsciously use any patterns you notice, and with just 10 possibilities the patterns are there. And you've been reading sequences of digits since you were old enough to get given pocket money. Vs long sequence of 16 possible tokens, of which 10 belong in one cognitive group and 6 in another. The extra 6 you've never memorized before in random order because they're for representing your language and that has other ingrained patterns. Let's not forget they admitted ipv6 addresses are too long and allow you to skip parts of it so now you have to count the colons carefully...

      You don't understand why a sequence of 39 digits might be harder to memorise than sequences of 10? 16 is longest of the examples that people actually memorise (no, people are not memorising their bitlocker keys), and even then they have 1 example that lasts at least 5 years to deal with, instead of however many IP addresses they have to deal with. Also many of my account numbers and my nations equivalent of a SSN are alphanumeric so 36 vs 16 choices.

    I could be wrong, but I do not think it's easier to remember 45465465464938259 then it is to remember the lyrics to a popular song. Now I assume there is some sort of brain difference playing here. But while looking it up most popular memorization strategies are either ram it into your head with repetition or converting it to songs, rhymes, poems, or other word phrases. It's quite easy to remember things like "Mmm-mmm, went the little green frog one day".

  Speaking of which, the slash notation has not gone away in IPv6 notation.
  • ghshephard 3y ago
    At least the user networks are /64s, so, to some degree, CIDR notation isn't relevant for someone just trying to set up their system - netmask is now always 64 bits. And sure, ISP/Network Engineers still care about /56, /48, /32, etc... but that's their day, and takes about a week to have it ingrained in a way that you almost never could with IPv4.

  > But also do you think is 24414.64517.21200.44298.46574.49887.23623.7394 is really that much easier to type? Or 231.22.96.68.14.229.38.41.242.44.72.220.156.50.232.95 if you keep to 8 bit octets? I mean... yes, actually; I can type those blindly on a normal numpad. I'm sure somebody somewhere has made a hex number pad, but realistically on any normal keyboard entering hex means going back and forth between number and letter keys.

    On QWERTY layouts, you can type ABCDEF with your left hand and 0123456789 with your right hand on the num pad.

      That would be really convenient if : weren't in the middle of the keyboard. Maybe hardcore IP typists need an alternate keyboard layout where * maps to :

  Microsoft did. The first example is pretty much what bitlocker recovery keys are.
