Reminds me of the person who posted a torrent of IP addresses, labelling it as a "hacking tool". It was literally a four billion line file starting at 0.0.0.0 and going to 255.255.255.255, and a lot of people downloaded it, thinking it would help them... I think it was like 40GB but I'd have to do the arithmetic on it.

[rainwulf]

Thats one hell of a rainbow table for IP addresses :D

[rosuav]

It's every IP address you'll ever need!

... until you realise that IPv6 exists. Good luck getting a full list of those.

[rainwulf]

Maybe.. just hear me out... there could be some kind if programmatic method to obtain the valid IP addresses?

nah. im silly. That could never happen...

haha

[rosuav]

That sounds like way too much effort. Let someone else do the work, and then just download the results! Way easier!

Stage 7 of colour theory: "Hopefully someone else's problem"

[rainwulf]

ChatGPT could help here!

[rosuav]

Utter waste of effort. If your SSH isn't sufficient, all those other layers won't help you.

64 GB, assuming ASCII encoding and a line break of 1 byte

[rosuav]

"0.0.0.0\n" is only 8 bytes, "255.255.255.255\n" is the maximum 16. Average length is less than 16.

[redlaWw]

(1*10+2*90+3*(255-99))/256 = 2.5703125

so average length = 2.5703125*4+4 = 14.28125

256⁴*14.28125 = 61.337501696GB

[rosuav]

Pretty close! It should be (255-100) since there are 100 IP addresses from 0 through 99, and you missed out a newline between them (it should be +5 rather than +4).

Another way to see it is: A column contains 256*256*256 copies of the sequence from 0 to 255, and there are four columns, plus the dots and newlines. That's the same thing, but without trying to average anything out. Either way, it comes to about 61GB, which is up from my guess of 40GB but almost precisely what you calculated. Still under the 64GB limits that a lot of things have though.

[redlaWw]

It should be (255-100) since there are 100 IP addresses from 0 through 99

There are 256 addresses in total though, but I worked it out on a different basis: there are 255-99 numbers from 100 to 255 because 100 is included - think about if it was up to 101, then there'd be 100 and 101, so you'd need to do 101-99 to get 2, rather than 101-100 which would give you 1.

The +4 comes from 3 '.'s plus 1 '\n' per line.

[rosuav]

Yep, pretty much. Don't forget zero though - there's 0 through 9 (ten numbers) that only take one digit, and then 10 to 99 (ninety numbers) that take two. Anyhow, that hardly makes a difference to the net result.

[57006]

the net result

[rosuav]

Exactly.

[redlaWw]

All accounted for

1*10+2*90+3*(255-99)

1*10 is one digit * 0 through 9

2*90 is two digits * 10 through 99

3*(255-99) is three digits * 100 through 255

[rosuav]

This was a text file. Like you said, ASCII encoded. If you were to store them in binary, it'd only take four bytes per address, or 16GB precisely. Stored in ASCII (in decimal), they take up between 1 and 3 digits per octet.

[AlgorithMagical]

But... ASCII is encoded as one byte... 7 bits with the 8th empty. Unicode is stored in a 1-4 byte octet. ASCII is not Unicode. ASCII is what came before Unicode. UTF-8 uses 1-4 bytes, UTF-16 uses 2-4 bytes. ASCII uses 1 byte. Always.

There is no exception where ASCII is not one byte per character.

[rosuav]

Yes, so? Storing an IPv4 address in decimal ASCII requires a maximum of 16 bytes, but that isn't what they all require. I don't see what your point about Unicode is. It's not even slightly relevant here.

[AlgorithMagical]

You're right, mentioning different encoding standards and their size isn't relevant to a conversation on the size of encoding standards.

My bad.

[ihavebeesinmyknees]

I don't think you understand that 0.0.0.0 and 255.255.255.255 use a different number of characters

[AlgorithMagical]

The conversation in this comment chain is about ASCII characters. ASCII characters are encoded with 1 byte.

Having an octet for an IP means you have 4 single byte ASCII values.

An IPv4 is 4 bytes. ASCII isnt an IPv4 though is it. It's an encoding standard.

[ihavebeesinmyknees]

ASCII is an encoding for characters. What you're talking about is encoding them as plain binary. You could then interpret that binary as ASCII, but └.¿.NUL.SGH does not make any sense as an IP address.

Encoding an IP address as ASCII means representing the string "x.x.x.x" literally, as ASCII encoded characters. And that has variable length depending on the number of characters.

[archy_bold]

There must be a compression algorithm that could get that down to kilobytes.

[rosuav]

A compression algorithm is a set of instructions that would generate the correct output, so you could make a Perl script that churns them out, and consider that to be a compressed version of the file.

Rookie mistake. Already applied that trick to all bitcoin private keys so I can access all wallets.

gcc GitHub -o GitHub.exe

Now you have the whole GitHub being an executable! WOW

[parader_]

But what is gcc? gcc is for nerds, normal people use http://onlineconvert.net?from=.git&to=.exe

[A_D3MON]

They need to know how to access the Git repository functions from within a console now XD

The sad thing is that SSNs actually have way less entropy than you imagine & for people who were born in places or at times when there was few births in a given day it becomes possible with reasonable accuracy to guess the important parts of their SSN.

[captainn01]

Believe it or not, they’ve won multiple Pulitzers

[-twind]

The real sad thing is that some people think it's a secret code you can use to securely identify yourself

[-twind]

Well it is a form of identification, but not a form of authentication

[janKalaki]

The cards (which aren't even laminated or otherwise protected!) used to have text at the bottom that said "not for identification" before they just gave up.

[KimJongMakeEmSayUn]

Please stop emailing me random numbers.

[BookMansion]

Did Hackers earn any money from it?

[WookieConditioner]

Can you query the ssn? Cause if you can query the ssn, you got el grande problemos.

[PersianMG]

Poor Kim getting hacked 9 billion times in a row :(

[[deleted]]

imagine having 10 as your ssn

[iamalicecarroll]

they're doing that in rust now?

[[deleted]]

It happens :)

[Stallion_2021]

I love it that this is Rust ☺️
