Yet another misuse of 1.1.1.1 in the figures.
Actually, it was a mistake NOT reserving more human-friendly IP blocks for documentation/example purpose. The three /24 blocks reserved all fail blatantly because nobody remembers them, and they look as unsuspicious as normal blocks.
1.2.3.0/24 would be a much better choice because people would easily remember them and know it's not "real", just like you would not take a phone number 123-4567 on a filled form as "real" (even though it might be).
Next time you make anything, please remember to design for human.
- tinus_hn 9y agoIf you make it foolproof, the world will just create better fools.
- ge0rg 9y agoExcept that everybody knows that the "fake" phone number prefix is 555: https://en.wikipedia.org/wiki/555_(telephone_number) https://en.wikipedia.org/wiki/555_(telephone_number) ;-)
- IncRnd 9y agoExcept that not everybody knows that. I use the # for information at stores, when asked for a #, and the cashiers usually have no idea what 555-1212 means. In my sample, the vast majority of people do NOT know.
- mulletbum 9y agoYou might be confusing "do not know" for "do not care."
- c22 9y agoYeah, my technique is to punch a random number into the machine, if it works then no problem, but if not the cashier will just scan the "store card" after the 2nd failure.
- IncRnd 9y agoThat's my technique too, but when the cashier asks to look up my number I give them 555-1212. That is what fed into my comment. Most people don't care what number is used, but many also don't know that 555-1212 is the secondary information number. This, of course, depends upon their age and geography. This comes up in the friendly conversations that result upon them looking up the phone number.
- discreditable 9y agoCashiers don't know, or don't care?
- IncRnd 9y agoOf course some know but don't care, but the majority I met don't know.
- michaelmrose 9y agoHow did you ascertain that they didn't know?
- IncRnd 9y agoBecause I was the one who provided the phone number and stood there talking with them.
- michaelmrose 9y agoHow do you differentiate not caring what number you gave them from not knowing? The fact that they showed no reaction is more of a sign of how few fucks are given rather than everyone else's ignorance.
- IncRnd 9y agoHow do you differentiate not caring what number you gave them from not knowing I said how in the comment to which you replied. Where did I say, "fact that they showed no reaction"? Why do you interpret something unstated as a fact?
- michaelmrose 9y agoBecause you failed to bother to give a more comprehensive answer when I asked how you knew I extrapolated. Did you personally conduct a survey?
- smudgymcscmudge 9y agoWasn’t 555-1212 the only 555 number that worked?
- mikestew 9y agoIt used to connect you to directory information (as in "I need to number for mikestew in Seattle...") for the specified area code (or local, if no area code specified). I don't know if it still works or not.
- jasonjayr 9y agoThere are other codes in there, caller & circuit id read-backs and other utilities the telco will use. They're usually private, but no serious harm if the public find out about them.
- isostatic 9y agoWhen I bought large items at crappy retailers like currys, the often refused to serve me without a postcode. I'd use SW1A 1AA, 2AA or 0AA Except when buying a TV -- that would be W1A 1AA
- IncRnd 9y agoExactly.
- isostatic 9y agoSadly the reverse lookup for 10 Downing Street is "Prime Minister and First Lord of the Treasury". I told the cashier "That's me, don't you recognise me without the makeup?"
- JorgeGT 9y agoYou should have said something like "note that the Chief Mouser to the Cabinet Office, albeit less known to the general public, also lives in the building", which is technically true.
- AllegedAlec 9y agoExcept that 'everybody' in this case only means people in North America, and, reading the siblings of this comment, not even all of them.
- codetrotter 9y agoNot only people in North America — I’d say everybody that has an above average interest in movies. In Hollywood they use 555-xxxx all the time.
- matte_black 9y agoExcept these days a real number is commonly used if it provides a marketing benefit, given how easy it is for people to pause movies and read all visible text.
- deathanatos 9y agoI'm watching Hawaii Five-Oh on Netflix at the moment, and the show regularly uses that prefix when a phone number is required for the plot. Makes me smile every time they do it.
- xellisx 9y ago555-1212
- oasisbob 9y agoWe haven't always had CIDR. Saying that not carving a single /24 out of a class A network is bad UX when variable length netmasks weren't even in use yet is a fundamentally silly misreading of history.
- isostatic 9y agoA whole 16 million IPs were allocated in 10.0.0.0/8 for private use, and "10" is pretty easy to remember. Trouble is people then used it. By the time 192.0.2.0/24, 198.51.100.0/24, and 203.0.113.0/24 were allocated in RFC5737, it was too late. IPv6 makes human IP addresses meaningless, but even they I believe they allocated 2001:DB8::/32 What a stupid address range for examples
- chiph 9y agoThe 10.x region is the reason that a former employer is such a huge user of NAT. They'd acquire a business who were also using that range, and they'd integrate the networks via NAT because it was too hard & dangerous to change the acquired company's devices & services.
