>ITT: babies first look at networking

first look...?
babies can't see

legacy compatibility

What the fuck
Explain

Do you think human babies are puppies?

You can represent IPv4 octets in many different ways. It's kinda crazy.
hexadecimal, dotted hex, decimal, octal bytes, dword, or any combination of them
plus browsers do all kinds of anti-phishing shit
so you can do stuff like 127.𝟎.𝟎.1/ and it will work

172.217.2.14
0254.0331.0002.0016
0254.0331.526
025466201016
0xac.0xd9.526
0254.14221838
0xac.14221838
0254.0331.02.016
0xac.0xd9.0x2.0xe
2899902990

loads more combinations...
¯\_(ツ)_/¯
Not as useful as it used to be because everything is behind cloudflare and they don't allow direct IP access.

Is there stuff like that in IPv6?

yes

what idiot thought that up

same people that MITM 10 percent of global web traffic

>PING: transmit failed. General failure.

>OK, why the fuck does this exist?
How to handle the compatibility with the existing system which is already deployed worldwide is maybe THE biggest concern to address?

It's good that they made it reasonably simple in most cases.

It's so programmers don't have to fuck around messing with ipv4 implementation in modern programs
You can just write a regular ipv6 stack and os will handle both ipv4 and ipv6 connections from that socket

they are, after all, a dns company

I think IPv6 FUCKING SUCKS
