They scale very well if you have enough addresses available. It is much
easier because you don't need a NAT/PAT table nor create concepts for
interconnecting LANs with RF1918 address etc.

It does very well, a home customer has about 2^64 addresses available.

Why do we need a hierarchical system here?
If we want addresses for local-only services we can use ULA. also more
than enough addresses available for all your needs.

That is what big companies and providers tells us. Everybody that wants
to use VoIP without any problems needs to be reachable from the outside.

Then they can operate an SPI firewall. Windows has one enabled by
default, most home routers have one enabled.

Why should it do NAT?

The grandma's router has an SPI fw enabled. Grandma's Windows has an
SPI FW enabled by default, so no problem.
If you have a good operating system, no server software runs on the
public addresses. Then there is also no problem at all without NAT or
an SPI fw.

Because of proxy servers and NAT companies like Facebook and Google
created other methods of tracking. They use User Agents, Cookies,
Browser storage to identify a user, they don't need an unique IP
address.

NAT first creates a flexibility and then you see how bad it is. Think
about DNS with servers that have private addresses and should have a
host name. You then need NAT hairpinning and other nasty stuff.

The main problem of that is that Windows has enabled server software
like NetBIOS over IP and SMB. This is the problem and NAT/SPI should
now solve the biggest security problem that MS was able to create?
Personally, I don't care anymore about windows machines because they
are insecure by design.

Then do it if you like a really bad network infrastructure.
What I wanna is that I can switch off IPv4 at all at my side without
having problems to connect to other's servers.

As long as /you/ are all right, screw the rest of the world?

It's fine to blame MS for a decades-long attitude where security is an
afterthought at best - you'll find few people who are particularly
impressed with Windows security (and even fewer in a newsgroup like this
one!).

But in one simple step, NAT eliminates a whole major class of security
issues for client systems (including Linux and other OS's).  It does so
in a way that is not only easy to get right, it is also hard to get wrong.

Security is not a feature - a one-off item that you attach to your
network.  It is a process, and it is a matter of layers and
combinations.  Each part reduces the overall risk of breaches - none is
absolute on its own, but in total you find an acceptable risk level.
And it is always a balance between keeping out the stuff you don't want,
while letting in the stuff you /do/ want with as little user
inconvenience as possible.  NAT plays an important part in the security
in a lot of systems because it provides a huge step at keeping out
unwanted stuff while being of very little inconvenience to most users.
And it does this for practically nothing - stand-alone NAT routers for
small networks cost peanuts, and any serious router for a big network
will do it with negligible delay or overhead.  There are not many
security measures that are so effective for so low cost.

Every SPI firewall does the same and costs the same. There is
absolutely NO security reason for NAT at all.
SPI works perfectly well and is included for IPv6 in every home router.
SPI also costs nothing but doesn't have the nasty things of NAT.

NAT wasn't intended for security, it was intended for expanding the
lifetime of IPv4.

I think that the second part of that is extremely germane:  "easy to get 
right" and more importantly "had to get wrong".

I read that statement a little differently and I think that it's worth 
sharing the idea.  Do something that implicitly breaks communications 
(e.g. incompatible addressing) such that you must do something that 
explicitly enables communications (e.g. NAT / proxy).

There is a lot to be said for a security system that requires explicit 
precise action to make something externally available while just about 
anything else will fail to communicate externally in one of many ways.

I say "just about" because even a blind hog finds a truffle on occasion. 
  Chaos also dictates that the dryer be folded when you open it for the 
first time.

I believe that David was referring to the security implications related 
to trust rather than the addressing of the underlying protocol.

If nothing else, based on population size of connected devices.

Site-local vs link-local immediately comes to mind.

I've used VoIP without any problem without globally routed addresses.

There is a difference in something being simpler / more pristine vs less 
simple / less pristine and still working perfectly fine.  The latter 
tends to negate the former as arguments for must have global reach ability.

I think that it's important to keep time & context in mind.  Windows has 
an SPI firewall enabled by default /now/.  It did not 20 years ago.

I will not bet my security on "good operating system" nor "no server 
software runs on the public address" /alone/.  Does "belt and 
suspenders" or "layers of security" mean anything?

I'm fairly certain that the User-Agent and Cookies headers pre-date wide 
adoption of NAT.  The definitely pre-date Facebook and Google.

Also, trusting the IP address alone is insufficient.  IPs used to be far 
more dynamic than they are today.  Thus you couldn't rely on them for 
identification in the vast majority of situations.

I guess setting up an internal zone to resolve the name to the LAN IP is 
"other nasty stuff".

Currently (2022) you will have better connectivity with IPv4+IPv6 with 
NAT than you will with IPv6 only.  Sadly, the Internet isn't even close 
to parity between IPv4 and IPv6 from a service availability standpoint.

I know, but the main problem already was and is still that Windows is

I know that, but I definitely don't rely on firewalling. I disable the
cause of the security issue and I don't try to make it less vulnerable
with a FW.

I also don't rely on them for auth, but i use them as an additional
criteria if possible.

Yes, that is what I mean because that often creates problems.
Forst, DNS uses caching and a computer that was outside my have the
public IP in its cache (TTL not expired yet) and will not ask the name
server again when coming to the internal net.
Then a computer doesn't need to use the specific DNS to resolve the
name. Maybe it is configured to use a specific DNS. Google Chrome and
Firefox offer DNS over HTTPS and maybe use that instead of the DNS the
computer gets via IPv6-RA/DHCP.

Full ack, it is really annoying that I still need to have IPv4
connectivity, especially when self-hosting my servers I need to access
from IPv4-only nets.

What /specifically/ is annoying?

What doesn't function to satisfactorily?

What do you want to change?

Why would you change it?

I'm genuinely asking in the spirit of discussion to understand and learn

I think that "by default" is the most operative part of that statement.

It's entirely possible to configure Windows so that it's considerably 
safer to have as a server.  But it takes effort and is decidedly against 
the default.  One of the first things to do is to unbind Client for 
Microsoft Networks and File & Printer Sharing from NICs.  }:-)

As well you should.

Fair enough.

I think that IPSec AH and / or ESP is a LOT better for authentication 
than IP.  That being said, I only allow IPSec from known endpoints that 
should be speaking it.  No need to expose services to the world where 
it's not needed.

Understood.

I'd be curious to know what client device is retaining local stub 
resolver cache when changing networks and therefore likely changing DNS 
server configuration.

Don't et me started on the over zealous use of DoH.  There are MANY 
aspects of enterprise networks which break when things naively assume 
that an outside the enterprise DNS server can provide the same DNS service.

Sadly, I think we're going to be in the current state for one to three 
decades.

Getting rid off NAT here to get rid off that gateway. With IPv6 I don't
need that and it is a much easier configuration.
Easier for me means more reliable because less things can get broken.

Full ack, that's what I do at work when I have a Windows computer for
specific applications.

I assume systemd-resolved does, I already experienced that with it. The
reason for that is that DNS with global resolved domains is intended to
equal regardless which resolver ask. For the caches I see no reason in
clearing the cache if the network comes up/down.

Completely agree, but if you have just one computer that isn't
administered by the company you need to emanate that some users don't
use your local resolver.

Maybe yes, but there is hope over the horizon, some big tech companies
implement IPv6 and I just wait until they say "we switch off IPv4 in
one year" or "websites without IPv6 connectivity will be unlisted from
Google".

What's more responsible for that problem?  SIP itself or NAT?  There are 
many other protocols that work through NAT perfectly fine without the 
need for such shenanigans.

It's been a while, but I think that it is possible for SIP clients to 
connect to a globally routed IPv4 address that is port forwarded / NATed 
to an internal server without the need for the NAT gateway shenanigans. 
But, maybe I'm mis-remembering things.  Maybe it was configuration of 
the SIP server saying "Report $THIS external IP."

I actively avoid systemd and it's ilk.

Ha!  I don't think we'll see big services turning off IPv4 any time 
soon.  I doubt we will see it in the next decade, if not more like two 
decades.

As long as there are more than a tiny percentage of IPv4 only clients, 
the big players will still have IPv4 connectivity.

SIP is a really horrible protocol. It should have been in an April
Fools RFC.

That is incredibly painful, especially if you want to _receive_ calls.

Maybe. Doesn't work with a dynmic IP address.

Yes. You're part of the party that makes sure it's going to happen
this way.

That does not mean that internal networks won't go single stack IPv6.
I don't mind having a handful of dual-stacked, internet-facing
servers.

Agreed.

I'll give you that it's painful from a technology and configuration 
standpoint.

But I disagree about the receiveing calls part.  There are MANY VoIP 
users that have done nothing that are receiving calls through this type 
of configuration.

The trick is that the calls come in over an established connection from 
between external server and the VoIP endpoint.

Is it as pure as the calls coming directly to the VoIP endpoint?  Nope. 
Did it stop Vonnage et al. from offering VoIP service to these types of 
VoIP endpoints?  Nope.  Does it work through indirect methods? Yep.

> Maybe. Doesn't work with a dynmic IP address.

There are multiple ugly solutions that allow dynamic IPs to work. 
Usually related to learning the (new) current external IP and 
re-configuring themselves / re-registering with the upstream VoIP server.

Again, see Vonnage et al. doing this for years.

> Why am I not surprised about that?
>

I think quite the contrary.  I advocate for IPv6 adoption.  I've adopted 
IPv6 on all my personal things for longer than I can remember.  I ask 
multiple vendors when they are going to start offering, much less 
actually supporting (as in help desk) IPv6.

I'm also quite realistic that we're going to have IPv4 for a LONG time.

> That does not mean that internal networks won't go single stack IPv6. 
> I don't mind having a handful of dual-stacked, internet-facing servers.

In some ways that seems like a disingenuous response.  It doesn't really 
matter /how/ you support IPv4, or /where/ you support IPv4.  The fact 
remains that you *ARE* supporting IPv4 in some way somewhere in your 
network.  If you're communicating with an IPv4 endpoint in any capacity, 
you are supporting the perpetuation of IPv4.

I'm sympathetic to your anger at NAT, but I think it's unrealistic in
this day and age to expect people to have _full control_ of their
local network. Some folks live with someone else (relatives, parent,
shared housing) who controls their network, other times you have
guests who join your network who are running things you have no
control over. When I was a kid hacking around, I was running all sorts
of insecure garbage (and writing insecure code (though that was a
different time)) on my machine.

You could try to partition your network into a "guest" subnet and a
"home" subnet and place a stateful firewall in front of the guest
subnet, but very few consumer router/AP combos offer a user-friendly
way to make this separation. (Happy to be proven wrong on this point.)

Even the $50 TPLink stuff can do a guest WiFi network, such as the
Archer A7.

Should take you right to chapter 8.1 "Create a guest network".

The main problem here is that most people don't care about their
network. Additionally, many ISPs only offer /64 prefixes and it is a
PITA to subnet them to 2 /65 because you then need DHCPv6 to address
your devices. The additional work isn't worth the goal here for most
people.

Last time I had a "whole home gateway" from the ISP, it'd give a
completely separate /64 to the "Guest WiFi" (if v6 was enabled on it).

That is the best practice, but sometimes not possible because the
customer only gets /64 at all.
