Can you explain this more? Why are you so tied to ipv4? I recently enabled IPv6 on my home network, and roughly 30-40% of all internet traffic goes through IPv6. Things are noticeably faster, especially connection times to online games on Xbox Live. My only complaint is that my ISP keeps changing the prefix every quarter or so, so my static addresses need to be updated in the firewall and other places. I am looking i…

> Can you explain this more? Why are you so tied to ipv4? For me, IPv4 doesn't break the privacy barrier, IPv6 blasts a huge hole straight into each and every household, office and IoT device on the planet. No, privacy fixes put into IPv6 do not work.

You're not completely wrong, but that ship has sailed a long time ago: https://amiunique.org

Until browser fingerprinting is addressed, there will be no real privacy.

I'm surprised it just got implemented! Since IPv6 is so popular and common nowadays.

My previous provider, I think largest in The Netherlands, ziggo rolled it out quite okay. Now I moved and switched providers, to much faster 1 Gbit (can go up to 8gbit but I dont know what to do with that yet until I have a 32K tv maybe) symmetric, but no idea when they will plan to roll out IPv6 on this network. I cannot say I really miss it, but have to admit my internet feels a bit incomplete :)

so I wish it was even more popular than you state. :D

Another person who does not understand IPv4. IPv4 isn't a text based protocol where IP addresses are parsed like DNS. It's a binary protocol where addresses are recorded in binary and adding more address space WOULD BE A BREAKING CHANGE.

Not at all. We could have taken one of the unassigned /8's at the time and allocated it to v6 transitional addressing (the failure to address 4->6 reachability is IMO why v6 failed). For the sake of this example lets use 53.0.0.0/8. All new addresses start with 00110101 followed by the first three bytes of the new v6 prefix. The prefix acts as a flag that indicates it is a new address and routers read an additional 5…

The next few months may be hard for you. AWS will start charging for ipv4 on February 1st, so it’s likely that either a mass migration is coming or prices for many services will increase accordingly to pass that cost along to customers.

I was implementing IPv6 networking at an ISP/VPS provider in my 20s including customized Xen network startup scripts(because they didn't support v6 or VLANS).

I'm turning 40.

The next few months will be fine.

You want a ULA (unique local address) instead of link-local. Link-local can sometimes mean needing to append the interface name to your address and a bunch of other weirdness. If you pick a ULA prefix and announce it (or assign some statically) everything pretty much just works. I’ve been using them internally for over a year and it’s been great, they basically feel like RFC 1918 addresses.

You'll also need a router that's not stuck in the 90's.

I never got IPv6 working well until I switched from pfSense to OpenWRT, due to my residential ISP switching prefixes very frequently.

For example, there was no way to get pfSense to not publish the public address of the router as the internal DNS, so every time the prefix changed internet effectively broke.

For a practical demonstration: That's the reason decimal IPs work, too - i.e. http://3520653007/ is the same as http://209.216.230.207/ (and both will go to HN) - it's all just nice formating for our human brains. Nothing would stop us from formatting IPv6 the IPv4 way except the monstrous length of the resulting address.

Wow learned something new today. What's interesting is that the decimal representation looks more like a phone number which people would be used to. Interesting that IP addresses as they are written today was the format that won, as a kid before learning how computers worked I always found it weird how 255 was the highest number in each group.

One of the features of IPv6 is address autoconfiguration, obviating the need for a central authority like DHCP on v4. However, that only works with a /64 prefix and given that larger sites might want to have multiple subnets, that’s why most assignments are /56 or /48. But still. If all assignments were /48s, that would still leave room for 281 trillion networks which even I believe is enough for the foreseeable futu…

> However, that only works with a /64 prefix Well it should be redesigned so it works all the way down to individual addresses.

There was a proposal for that: https://www.ietf.org/archive/id/draft-mishra-6man-variable-s...

I'd even go out of my way and say that undecillion of IP addresses ought to be enough for anybody.

Bold prediction! Let's see if it holds true in 200 years when every cybernetic cell in your body is individually addressable from the public internet.

This is almost IPv9 (RFC1606)! https://datatracker.ietf.org/doc/html/rfc1606

   The up to 42 deep hierarchy of routing levels built into IPv9 must
   have been one of the key features for its wide deployment. [...]
   As yet, no requirement has been found for levels 40-42, with level 39
   still being used for experimental interrogation of atomic structure
   of components where required.
Of course, it's a 1st April RFC. For those who don't know them, see https://en.wikipedia.org/wiki/April_Fools'_Day_Request_for_C...: they include thinks like terminals with subliminal messages, IP over pigeons...

You can use DHCPv6 instead of SLAAC if you need autoconfiguration on sub-/64 prefixes.

Some systems like android don't support anything but SLAAC

IMHO it means that they are not fully IPv6 compliant. Corporate networks often have DHCPv6 rather than just SLAAC.
