Unless you /actively/ disable IPv6, there is a very good chance that 
IPv6 is enabled on contemporary devices /by/ /default/.

I remember when Microsoft started enabling IPv6 by default on server 
OSs.  It was possible to ignore it for a while.  But then things started 
to try to use it.  As such, it required active management or active 
disabling.  That was 10-15 years ago.

Do you guys know that Microsoft stopped testing Windows in IPv4 only
environments years ago? Do you really want to run all those untested
code paths?

If I remember correctly, on premises Exchange isnt even supported any
more in IPv4 only setups.

No, I was not aware of that.

I feel like the IPv4 code paths are (quite close to) the same in both 
IPv4 only and dual IPv4 and IPv6 environments.

The first MUST HAVE IPv6 issue I ran into was related to Microsoft 
Exchange.  I think it was a 2003 or maybe 2008.

Back when I first ran into the MUST HAVE IPv6, I was able to get away 
with a link-local IPv6 address in an otherwise IPv4 only environment 15 
years ago.

It definitely works without global IPv6 connectivity, but sometimes
uses link-local IPv6 to communicate with other Exchange servers.

It isn't needed. You can enable it by setting the A flag for a prefix,
but a network works perfectly fine without SLAAC. Just don't set the A
flag for the prefix, but set the M flag in the Router Advertisement to
tell the computers that they should contact a DHCPv6 server via
link-local multicast. I already tried in a test environment with ULA
addresses.

I have seen people use something other than /64 on networks as memory 
protection against exploding a neighbor cache on a link with very few 
systems.  E.g. a mostly point to point link using a /120 ~ /124 or even 
a /127.  Particularly on non-point-to-point links that are used as 
point-to-point links, e.g. Ethernet cross over cable.

The reason for the /120 ~ /124 is to allow multiple / redundant devices 
on either end.

Yes. One can detect networks built by experienced IPv4 people by
seeing multiple /120 crammed into a sincle /64 address space to "save"
addresses. Experienced IPv6 people will reserve a /64 per transfer
network and just use a /120 from that.

I've seen people use /128s out of a single /64 for (primary) loop-back 
addresses on all their routers.

I bet you'll find some more exceptions if you look closely enough. But
that's just proving the rule.

This is just choosing a different prefix for your network. There is no
magic in that.

But to do that correctly you need to be aware how subnetting works.
You need to understand what /<any number> means etc.

Yes, agreed. IPv4 subnetting is more than just knowing that.

I don't think that we need to make them forget.

Contrarily I'd rather they remember how to do it, but choose not to use it.

Do we actually want people forgetting that sticking their hand over / 
into an open flame is painful?  I don't think so.

There is also the fact that the sub-network concept applies equally well 
to IPv6 as it does to IPv4.  We just have different grouping sizes that 
we use by convention.  But the binary math therein, that's still 
important to know, independent of 32-bit and 128-bit.

I don't know that I agree with that.

Many people will not inherently derive that B is better than A or that A 
is worse than B.  This seems to be especially true when people are in 
the frame of mind to ingest information without actually processing it. 
As such, we need to give them both A and B as well as C wherein C is the 
pros and cons of A & B.

We hope that it's the /internal/ interface.  I've seen it on the 
/outside/ interface.  >:-|  --  That was one of the earlier CGN

Classful thinking is harmful to today's networking, even in the IPv4
world. It is bad to examine people in a discipline that they will
never actively need. That is only relevant for historians.

I disagree on multiple fronts:

1)  There is a *HUGE* /difference/ in explaining what something is 
verses advocating for it's use.

Point in case:  Marc, you couldn't be as strong an advocate against 
classfull networking if you weren't aware of it.

2)  Most people need at least some understanding off why something is 
bad in order to choose not to sue it.  That is predicated on having a 
minimal understanding of what said thing is.

3)  If people have never been exposed to something, much less why it's 
bad, there is a reasonable chance that some of them will either 
re-invent (a variant of) it or discover it and take it up as a good idea.

All three of these require some very basic knowledge of what clasfull 
networking is.

I agree.
Also it is helpful to know the history to know why the default mask in
Windows is depending on the IP address entered. I also only understood
that after knowing what classful IPv4 is.

All you nee to know about this is "Windows is going to paste some
wrong value in the netmask/prefix field, just ignore it and enter the
correct value".

I want people to stop knowing about it. It has been irrelevant in the
internet for nearly three decades. You are free to run your own
private internet with classful addressing as long as you don't try to
connect to the Internet. Then pain begins. If you don't know about
classful networks, you're not tempted to use that knowledge.

Not knowing is fine.

>bad, there is a reasonable chance that some of them will either

I am not against telling people in the last hour of class "now that
you know how things work, I'm going to tell you how things started.
This is just a history lesson, don't ever try to implement this on the
Internet."

You just contradicted yourself.

If you want people to stop knowing about it then you also want to not 
tell them about it at any point in class.

If you want to provide the history lesson -- ostensibly for those that 
care -- then you don't want people to stop knowing about it.

So, which is it?
