Happy 30th birthday to RFC 1631 ("NAT"), the "short term solution" we all rely on (datatracker.ietf.org)

From the conclusion:

NAT may be a good short term solution to the address depletion and scaling problems. This is because it requires very few changes and can be installed incrementally. NAT has several negative characteristics that make it inappropriate as a long term solution, and may make it inappropriate even as a short term solution. Only implementation and experimentation will determine its appropriateness.

there is no fix more permanent than a temporary one.

edit: as I literally sit here inspecting the nat tables on a couple of edge routers.

That temporary fix will eventually become unnecessary. IPv6 has slowly getting more and more use.

Last week I was peer pressured into trying out Helldivers 2 (yes, this is relevant, trust me), so I downloaded it, installed it, and fired it up with no issues. Set up my preferred control schema with no issues. Played the torturial with no issues.

Then came time for joining my friends in multiplayer. Issues! No matter what I did, I couldn't seem to join them. Nor could they join me.

I verified the installed files, I tried to connect via my phone to rule out ISP issues, and I tried all of the different versions of proton, but the result remained the same. I simply couldn't join my friends.

I don't remember what caused me to go down the right path of troubleshooting, but I've always dosabled IPv6 on my linux installs. So I re-enabled it. The problem remained. Then I realized that I had it disabled in the kernel via grub command line flags, so I cuanged that and gave my PC a reboot. Success!

So, despite networking being a large (maybe even the largest) part of my vocation for the past two decades, last week was the first time ever I actually NEEDED IPv6.

torturial - I like that. Sometimes a tutorial is indeed a torturial. 😊
