What excuses are you referring to?
Are you also arguing that if a problem isn’t in your immediate periphery then it doesn’t exist? We are all human beings, living on the same planet.
There’s nothing wrong with feeling a modicum of empathy for those less fortunate by circumstance of geography or socioeconomic influence.
Even more simply:
Government: closes their curtains in the evening.
They’re not more effective. They might assist with speed of absorption but that’s it.
Never trust the network in any circumstance. If you start from that basis then life becomes easier.

EDIT:
I’d like to add a tangential rant about companies still using shit like IP AllowLists and VPNs. They’re just implementing eggshell security.
I actually disagree. I only know a little of Crowdstrike internals but they’re a company that is trying to do the whole DevOps/agile bullshit the right way. Unfortunately they’ve undermined the practice for the rest of us working for dinosaurs trying to catch up.
Crowdstrike’s problem wasn’t a quality escape; that’ll always happen eventually. Their problem was with their rollout processes.
There shouldn’t have been a circumstance where the same code got delivered worldwide in the course of a day. If you were sane you’d canary it at first and exponentially increase rollout from thereon. Any initial error should have meant a halt in further deployments.
Canary isn’t the only way to solve it, by the way. Just an easy fix in this case.
Unfortunately what is likely to happen is that they’ll find the poor engineer that made the commit that led to this and fire them as a scapegoat, instead of inspecting the culture and processes that allowed it to happen and fixing those.
People fuck up and make mistakes. If you don’t expect that in your business you’re doing it wrong. This is not to say you shouldn’t trust people; if they work at your company you should assume they are competent and have good intent. The guard rails are there to prevent mistakes, not bad/incompetent actors. It just so happens they often catch the latter.
Honestly, these days I have no idea. When I said “wouldn’t recommend” that wasn’t an assertion to avoid; just a lack of opinion. Most of my recent experience is with Cloud vendors wherein the problem domain is quite different.
I’ve had experience with most of the big vendors and they’ve all had quirks etc. that you just have to deal with. Fundamentally it’ll come down to a combination of price, support requirements, and internal competence with the kit. (Don’t undermine the last item; it’s far better if you can fix problems yourself.)
Personally I’d actually argue that most corporates could get by with a GNU/Linux VM (or two) for most of their routing and firewalling and it would absolutely be good enough; functionally you can do the same and more. That’s not to say dedicated machines for the task aren’t valuable but I’d say it’s the exception rather than rule that you need ASICs and the like.
I agree. GeoIP was never a good idea, but here we are. Any ASN could be broken up and routed wherever (and changed) but it’s still far too prevalent.
I might be misunderstanding. It’s definitely possible to have as many IPv4 aliases on an interface as you want with whatever routing preferences you want. Can you clarify?
I agree with your stance on deployment.
Given how large the address space is, it’s super easy to segregate out your networks to the nth degree and apply proper firewall rules.
There’s no reason your clients can’t have public, world routeable IPs as well as security.
Security via obfuscation isn’t security. It’s a crutch.
This article is biased to selling you more F5 equipment but is a reasonable summary:
https://www.f5.com/resources/white-papers/the-myth-of-network-address-translation-as-security
Long story short is that NAT is eggshell security and you should be relying on actual firewall rules (I wouldn’t recommend F5) instead of the implicit but not very good protections of NAT.
I can potentially see that scenario if your transit provider is giving you a dynamic prefix but I’ve never seen that in practice. The address space is so enormous there is no reason to.
Otherwise with either of RADVD or DHCPv6 the local routers should still be able to handle the traffic.
My home internal network (v6, SLAAC) with all publicly routeable addresses doesn’t break if I unplug my modem.
Hurricane Electric have a free tunnel broker that is super simple to set up if you really want to get on the bandwagon.
Though honestly I’d say the benefits of setting it up aren’t really worth the trouble unless you’re keen.
IMO they shouldn’t have allowed ULA as part of the standard. There’s no good reason for it.
It also means you no longer need the kludge that is NAT. Full E2E connectivity is really nice – though I’ve found some network admins dislike this idea because they’re so used to thinking about it differently or (mistakenly) think it adds to their security.
At the cost of leg room.
This book helped me out significantly:
Yes.
I used Netscape “back in the day”. With some interim transition attempts including the likes of Opera, I eventually switched to Chrome because it was genuinely more featureful and faster.
I was a happy Chrome user until they decided to deprecate manifest V2 and fuck up my ad blocker, at which point I switched to Firefox and haven’t looked back.
Everything in this industry is circular I guess.
Your comment is painful to read.
