Hello IPv6: a minimal tutorial for IPv4 users

IMO, IPv6 sucks for home users and labs. Prefix delegation means your routable IP scheme could change underneath you, and firewalling connections using PD addresses is really hard (unpredictable prefixes, privacy extensions change suffixes constantly), though some routers make it easier, like Google Wifi. I think most will end up NATing a single external IPv6 with a private IPv6 network behind it.<p>I wish IANA and friends would let home users and other smaller entities request global &#x2F;56 address blocks and force ISPs to peer&#x2F;announce (nothing crazy, just a default route).<p>EDIT: end users should be able to request static blocks from their ISPs for free, not IANA.

Anyone have any recommendations for a beginner who would also like to learn what&#x27;s meant by ARP, NDP, ethernet, and basically everything. I&#x27;ve been a developer for decades, and I understand the top level of http[s] well enough, but networking is basically a mystery to me.

I&#x27;ve been looking for a summary like this for years. I&#x27;m quite comfortable with IPv4, but haven&#x27;t understood IPv6 well enough to start using it in my home network. Thanks for sharing, going to read this over a few times to make sure I understand everything completely.

Can someone forward this to Verizon? They can&#x27;t seem to find the &quot;Enable IPv6&quot; button with their head so far up their...<p>Ahem, I&#x27;m quite frustrated with my provider :). But sanctioned monopolies are a serious drag on moving tech forward. Even if IPv6 isn&#x27;t a panacea, things need to be more agile than this if we&#x27;re going to really innovate.

This is very digestible, thanks so much for this. I&#x27;m going to set up a little test IPv6 network this weekend and play around!

This reminded me to re-check for the first time in a year or so which sites I frequent are now dual-stack IPv4 and IPv6. Surprisingly Hacker News is one of the few that isn&#x27;t these days...

&gt; In IPv4, multicast addresses are used, there is no concept of broadcast address<p>I think there&#x27;s a typo there, and the author meant IPv6, right ?

Amusingly apropos: Visual Studio Code was hanging when opening a remote session on my Raspberry Pi.<p>Turns out I had added &quot;AddressFamily inet6&quot; to the ssh config for connections from my laptop to the Pi. Once I changed that to &quot;AddressFamily inet&quot;, it worked fine.

the difficult part with ipv6 is that we can&#x27;t use it as a url, contrary to ipv4, so what&#x27;s the use ?

So in essence privacy extensions (hiding of internal network) are available, but disabled and unsupported by default.<p>Another thing are incoming connections - first thing i do with new router is disable UPnP, so clients cannot drill ad-hoc holes into my private network. How to do that with ipv6 network?

&gt; ...This post is aimed for home and small office networks. So if you know about ARP, DHCP, and NAT, and if you wonder how these work in IPv6 networks, this post is perfect for you.<p>Hardly a home user friendly introduction. An acronym soup begins right at the start, where the author describes his network setup.<p>Not sure if users would feel convinced to adopt IPv6 on their networks without understanding the benefits first.
