We don't talk about IPv5
-
I wrote and ipv6 parser once.
Never again.
As in a regex or ..?
An ipv4 parser would also be sorta difficult.
you have to account for the fact that all the octets can be added to decimal: http://2130706433 (valid 127.0.0.1)
or the fact that octets can be in different formats: http://0x7F.0x0.0x0.0x1 (127.0.0.1)
or the fact that you can mix octet formats: http://0xC0.0250.0.1 (192.168.0.1)

Is this IPv5?

The reason IPv6 was originally added to the DOCSIS specs, over 20 years ago, is because Comcast literally exhausted all RFC1918 addresses on their modem management networks.
My favourite feature of IPv6 is networks, and hosts therein, can have multiple prefixes and addresses as a core function. I use it to expose local functions on only ULA addresses, but provide locked down public access when and where needed. Access separation is handled at the IP stack, with IPv4 it’s expected to be handled by a firewall or equivalent.
My favorite feature of IPv6 is that there are so many addresses available. Every single IPv4 address right now could have its own entire IPv4 range of addresses in IPv6. It's mind-boggling huge.

Yeah a mix of regex and heuristics to validate before parsing
It was a long time ago now
It also had to parse ipv4 because they can be embedded (IIRC) and the different octet formats

Surely we can do better. Why not IPv10? That's 4 higher than 6!

Fun fact: IP version 5 is actually reserved for the Internet Streaming Protocol.

My favorite thing to use IPv6 for is to use the privacy extension to get around IP blocks on YouTube when using alternative front ends. Blocked by Google on my laptop? No problem, let me just get another one of my 4,722,366,482,869,645,213,696 IP addresses.
I have a separate subnet which is IPv6 only and rotates through IP addresses every hour or so just for Indivious, Freetube and PipePipe.
This is exactly why ipv6 was never widely adopted. There's too much power in a limited IP pool.

I see your satirical IPv6 meme and raise you the highest quality IPv6 evangelism you'll ever see.

That's nothing that can't be done with a good set of firewalls on IPv6.
wrote on last edited by [email protected]Good luck trying to find industrial stuff that supports IPv6, hell most of it is still serial.
I have legit heard that serial is security mechanism because it cannot communicate long distance like ethernet.
Of course you can do IPv6 magic that hides IPv6 from the end device, but nobody understands how that magic works.

Was?
It's still in progress..
I'm fully transitioned. The first step was getting an Internet provider that featured it. I had to change providers for that. Then I had to find equipment that worked. Some of the things that have an early implementation of IPv6 don't actually work. It's like they never actually tested it. Then I had to integrate IPv6 in the way everything worked. I'm a big user of unique local adresses, which I feel isn't a really well known feature.

not sure if you're aware thats a real thing https://www.ipv10.net/

wrote on last edited by [email protected]you could assign every square meter of the planet an ip and use it for location, and still have addresses left over

Guess we have to crank it up to 11, then.

If you don't have ipv6 internally, you probably can't access ipv6 externally. 6to4 gateways are a thing. 4to6? Not so much.
And this is why ipv6 will ultimately take another 20 years for full coverage. If it was more backwards compatible from the starting address-wise then this would all have been smoother. Should have stuck with point separators. Should have assumed zero padding for v4 style addresses rather than a prefix
If you don’t have ipv6 internally, you probably can’t access ipv6 externally. 6to4 gateways are a thing. 4to6? Not so much.
I'm pretty sure stateful gateways do exist, but it's a massive ball of complexity that would be entirely avoided if people just used native v6.

In progress?
I can't even get an IPv6 address, even if I wanted to pay an obscene amount for a business tier.
You can get on IPv6 for free with a HE tunnel https://tunnelbroker.net/

I hope nat burns in hell when ipv6 will become standard

And I would consider a detailed argument on why it is more secure to disable it to be a good reason.
Personally? I consider an IT team who don't know how to secure an ipv6 enabled network to not be competent. But that is a different conversation.
It has less eyes on it due to it being less popular. It also introduces an extra vector of attack.

Wait until we have IPv8, that‘s gonna byte us in the ass for real

Oh, now that you mention it I've never tried to map a static DNS entry to a device without DNS. Welp, time to get thousands of raspberry pi's to act as IP KVMs!
That would imply en existence of display/usb outputs…
We’re essentially talking a bunch of embedded devices talking to each other. You can give them all the dns entries you want, but if they (or the programming environment) don’t support DNS lookup you might as well put your dns server in excel.
