Really, all should block IPs coming from North Korea completely. (I wonder why they have gotten IPs...).

As if any legitimate hacker uses their own IP address.
The modern hack is done through botnets. The only way to trace them back to an ip is to have another hacker on the other side datamining the route being used while the connection is open.


Not the point I was making. Why do they have internet access at all? I doubt the normal guy in N.Korea has *any* chance to get internet access and even if, it is totally controlled by the government which makes it not a "real" internet access for me as most probably the government has white-/blacklists of allowed sites.

I wonder why they got IPs, really.

 

Ah, Wikipedia supports what I was thinking:

 

"Usage of communication technology is controlled by the Ministry of Post and Telecommunications. An adequate nationwide fiber-optic telephone system with 1.18 million fixed lines[301] and expanding mobile coverage is in place.[302] Most phones are installed for senior government officials and installation requires written explanation why the user needs a telephone and how it will be paid for.[303] Cellular coverage is available with a 3G network operated by Koryolink, a joint venture with Orascom Telecom Holding.[304] The number of subscribers has increased from 3,000 in 2002[305] to almost two million in 2013.[304] International calls through either fixed or cellular service are restricted, and mobile Internet is not available.[304] Internet access itself is limited to a handful of elite users and scientists. Instead, North Korea has a walled garden intranet system called Kwangmyong,[306] which is maintained and monitored by the Korea Computer Center.[307] Its content is limited to state media, chat services, message boards,[306] an e-mail service and an estimated 1,000-5,500 websites.[308] Computers employ the Red Star OS, an operating system derived from Linux, with a user shell visually similar to OS X. North Korea's only Internet café is in Pyongyang.[308]"

how hard would it be to completely cut all internet access going to NK, Iran and other places like that?

don't they need fiber optics or other means to connect to other servers? or thet use sat?


In short, this is easily possible via routing protocols :) No need to cut cables or something. But the internet is mostly "made" and maintained by people who don't really care for politics and with a thinking that restrictions are a bad thing (which they are).
