>How did IPv4 and NAT play any role in the dominance of Facebook, Airbnb et cetera? Very directly, I would say, by making the barrier to running your own low-traffic website too high. Modern social media is all about hosting content - microblogs, photos, etc. Geocities was an early workaround to an inability to host things, and it's worth remembering that MySpace was originally positioned as a kind of evolution of th…
The barrier is from the tools, not NAT. Maintaining your own server is prohibitively difficult for pretty much anyone besides niche technology enthusiasts or IT professionals. > Were it not for NAT, I would have expected an explosion in tiny self-hosted personal sites around the time that dialup was replaced by always-on cable connections NAT never stopped you from port forwarding 80 to your local server and many peo…
Also, port forwarding is _hard_. It might not seem like it to us more experienced people, but it's a problem that's not very googlable because there's a billion different admin interfaces for routers, and they all do it differently enough that you have to understand what you're doing, not just follow a guide, to port forward.
In contrast, if it was possible to make some simple software which regular people could install on their personal PC, and then they got a WYSIWYG website editor, and that software handled all hosting gave the user a link (ip address) to their website which they could send to friends, I imagine a lot more people would experiment with web publishing. Obviously, in order to run a site 24/7 on a dedicated server with its own domain would still be prohibitively hard for many people, but people would've at least been able to experiment and play with hosting their own simple website which they can share with friends.
