DNS is like have a Contact List. It's a service that saves all of your friends phone numbers to convenient names. So you can type in their name to find them instead of memorizing their phone number.
If you know your friends phone number you wouldn't need the contact list service.
That's how this works except the Contact List saves website names (like neopets.com) with IP Addresses (instead of phone numbers).
We think that their 'internet shutdown' will be a soft shutdown, only in the form of shutting down some of their DNS servers, sort of like ripping up a phonebook. People would type in google.com but there'd be no phonebook to get the correct IP address for that domain. This trick is like making your own phonebook.
For them to ACTUALLY FULLY take down the internet would be unfeasible according to what I've heard.
Correct, it's much easier to bring the internet down than people think. Some BGP routers disabled, coupled with a few select fiber lines and that would be that.
And back on the topic, DNS isn't the "internet", generally speaking, it's a tool to help humans -- it simply maps human readable names to IP addresses, yes some of us know there is more, but that is it's purpose in a nutshell. The internet and internal networks do not require DNS to function, it's all about the IP packets(TCP and UDP), a connection method(wire, fiber, radio wave) and some hardware addressing.
As with anything posted on this site, don't take everything here as gospel, do yourselves a little favor and engage in some reading up on the networking topic or watch a video. Even if you aren't a crusty old engineer, the high level view is pretty fascinating on how it all works, and the origination of why there is even an Internet today. Also read up on the history of unix/BSD/solaris/linux, and you will get a pretty decent idea of how your OS works, even shitty windows.
Also, the WWW isn't the "internet" either. There's also FTP, Telnet, Gopher, Ping, Finger, and more. Also, there are still a number of old-time BBS systems still working via dialup. US Robotics still makes modems, but they are USB dongles now. You can get one for less than $40. But you'll need to research the BBS numbers now before the info is gone.
I was on the internet before the WWW. There's nothing like using telnet to run software on a computer physically located halfway around the world, or using finger to see how many Cokes are in the drink machine in a physics building at some university in another state.
If the internet is down, it doesnt work. If the central DNS servers go down or are messed with, but the underlying network backbones and providers are still ok, it should however work to reach here and p.w
The issue with Cloudflare is that they use the same IP address for multiple websites, so the request must also contain a header telling Cloudflare which website you want to see.
If Cloudflare was actually down as well, I don't know where the IP number would go to.
Your connection to the Internet is up, but servers on the Internet which allow you to find the greatawakening.win server at address 63.21.56.102 (for example) are down, so you have this local static mapping (which is included on all machines) that tells your system what the IP addresses are for specific domains. Every system checks this file before sending a request to a DNS server, so if the DNS servers are down this will allow you to still connect to some important sites.
They can't take out the whole Internet which consists of a physical infrastructure and nodes residing on that infrastructure. However, everyone needs DNS because they can't remember IP addresses, and DNS is sort of a weak point in the whole Internet architecture because it has no security and everything relies on it, plus most of the public servers are in the hands of corporate entities. If they simply deleted the entry for greatawakening.win from the server that originally hosts the DNS then nobody could reach the site without an IP address.
If the internet is down how does this work?

Excellent analogy
Thanks. I teach this stuff to young adults and have tons of them.
So the internet connectivity isn't taken out then? Just the servers?
That's what this prepares you for.
Disabling the entire copper infrastructure of a small country is nearly impossible let alone ours.
If they go down due to dns server then yes. Basically the network is still up but you can't connect through normal means without the IP address.

Not impossible. Think solar winds hack, backdoors in router hardware, killswitches

PS IPX/SPX sucks.

How do you know it's protected by Cloudflare? I've never seen a Cloudflare waiting screen.
Type the IP for GAW in the URL bar and see:-
172.67.145.123
Does not work.
Edit:- Maybe it will work with an edited hosts file but I have not tested it.
IF DNS goes down I am hoping Yandex DNS is up:- 77.88.8.8, 77.88.8.1
I have also archived locally many small, obscure DNS services.
nice
Yes, it will work with an edited hosts file.
