Very theoretical question.
Practically it is not possible in the vast majority of countries in the world.
I guess if there is no electrical power In the entire country…
Internet access could be disabled in a couple of ways (but not limited to)
- By ISPs
- By Cloud providers as more and more people are using them
- By government organisations
But the whole concept of internet will carry on IMO. After all, its just a large LAN.
Technically it’s a bunch of LANs that are connected to each other
A Wider and less Local LAN, if you will
The internet is very resilient at this point.
You would probably need to drop a couple of nukes or orchestrate a combined strategic takeout of thousands of sites
Instructions unclear: nuked every city.
Chill, Gandhi.
Please be the chilling now, here today
Kill top level dns
But you could still connect with IP addresses and only the name resolution would get affected right? Please correct me if I’m wrong.
Yes, good luck remember thousands of IPS.
Also, no, all modern websites depends on external resources based on names, all websites would be crippled.
I mean I feel like it’s kind of hard to define what “the internet” really is because it’s so decentralized. Like if you cut all the undersea cables and split the internet into multiple parts, which part is the real internet?
And even if all the commercial ISPs went away, people could still connect their networks together through phone lines or mesh networking so it would be hard to say the internet was really gone
It used to be possible as networks could advertise that they owned IP ranges that they didn’t actually own using BGP, which is what’s used for high level routing. This is what China did around 2010 where they allegedly routed all the internet traffic in the world through China for like 10 minutes. I guess somebody could do that and then just drop every packet.
I expect that’s not possible anymore though, but I’ve been out the game a while so I don’t know for sure.
Just mess with BGP announcements
You can isolate the networks that are part of the Internet by switching off the submarine communication cables. They are considered a military asset by the countries and defended as such.
Yeah, just unplug your modem.
That’s an excellent idea! It’s a pretty badly failed experiment.
with traffic whitelists
There is an episode of The IT Crowd that explains how to do it.
With a sufficient amount of explosives everything is possible
If states isolated their network infrastructure from other states, the essence of international network would be lost.
Each country would have their own intranet, like Kwangmyong in the DPRK.
