@kevin but AAAA can also be a battery
@JennyFluff @kevin *nodnod* the stylus for the Microsoft Surface needs those.
@JennyFluff @kevin so can A according to Wikipedia 😱
@NiklasMM @JennyFluff @kevin yep. They're all dry cells. A 9V battery is just 6 AAAAs wrapped in a rectangular package.
@JennyFluff @kevin literally had a discussion about this yesterday after someone from our assembly went to the Media Markt for AAAA batteries for a tablet pen 😂
@kevin TIL that A and AAAA are actually both: https://en.m.wikipedia.org/wiki/List_of_battery_sizes

@kevin anonymous alcoholics like,

@kevin This naming scheme for DNS actually comes from the fact that DNS Records are written in these said batteries and these batteries are then placed into the nameservers.

right?

@kevin

AAAA - uncommonly used battery and dns record

@kevin now the logical question – AAAAA: DNS record or battery?

@cuu508 @kevin by extending from the given info its:

AAAAA: battery
AAAAAA: battery
AAAAAAA: DNS record

@chris
Unlikely. If there is next DNS address record, it is extremely likely going to be using a power of two (so at least "AAAAAAAA")... Originally "A" (address) DNS record is for IPv4 (which has 32 bits), and since IPv6 has 128 bits (i.e. 4 times as many bits as original one) its address record was named with 4 times as many A letters (i.e. "AAAA"). Yes, that's how we computer geeks have fun naming things! #IPv6 #DNS
@cuu508 @kevin
@mnalis @cuu508 @kevin And everything between ist battery sizes? And the batteries get increasingly smaller?
@chris @mnalis @cuu508 @kevin A23 (obviously you shorten it at that point) is a battery, adding further evidence for this theory

@kevin D - battery to be thrown at non-working DNS.

@kevin so AA and AAA batteries are therefor two and three times respectively the size of a single ipv4 address size (32 bits). This makes so much sense, thanks!

@kevin
Don't forget:

AAA Prime (Triple A) by rating agencies.

@kevin Aren’t they all dry cleaning or automobile towing businesses in the local Yellow Pages directory?
@neilo My father used to work for a company that repaired TVs and other consumer electronics (decades ago, when people still did that). It was named A-Amphi TV, for the same reason.
The first two are also bra sizes @kevin

@kevin @sesivany

AAAA: A DNS record, server powered by AAA battery

@kevin
AAAA.....

The sound you hear when somebody jumps off the roof because he cannot distinguish between DNS record and battery.

@kevin all four of them are actually batteries.

@kevin Batteries and DNS records not included.

@kevin

I accidentally ordered AAAA batteries once. I still have them. Never seen thing that takes them.

@swope @kevin so far I have only seen tablet styluses and pen-sized flashlights use them.

@kevin *ahem* cells, not batteries 😉
@kevin Confusion is discovering that there was an era of stylus tech that used AAAA batteries.
@kevin These are also all Minor League Baseball leagues
@kevin my Surface pen takes AAAA batteries. I didn't know they existed until it died and needed a replacement.

@kevin I had a Bamboo Ink stylus pen, which uses AAAA batteries.

Apparently there's an A size as well though. TIL

@kevin @danb I remember A batteries for my childhood cassette recorder, and AAAA batteries for my MP3 player. (About at the same time as the latter I also learned about AAAA DNS records.) Am I old or are you young?
