[C++]Deleting Internet Loop

[Stup]

Just mucked around doing some looping stuff tonight... was thinking this would be a way to generate all the ip's on the internet at the click of a button... write it to a file called hosts in C:\Windows\System 32\drivers\etc and essentially delete the internet for a user lol

#include <iostream>
#include <fstream>

using namespace std;
ofstream outFile;

int ip1 = 0, ip2 = 0, ip3 = 0, ip4 = 0;

int main()	{
outFile.open("hosts");
	while (ip1 < 256)
	{
		//reset the ip ranges back
		if(ip4 > 255)	{ip4 = 0; ip3++;}
			if(ip3 > 255)	{ip3 = 0; ip2++;}
				if(ip2 > 255)	{ip2 = 0; ip1++;}
		
		outFile << ip1 << "." << ip2 << "." << ip3 << "." << ip4 << endl;
		ip4++;
	}
}

output is something like whats below all the way through to 255.255.255.255 so i donno much about IP's and stuff but if this went through all posible combinations from 0.0.0.0 - 255.255.255.255 that could do some damage to a nub couldn't it ?

You'd atleast need to put a hostname aswell, and hope that the file isn't write protected ;).

Users can, though, just delete the file and use internet again ^^

Also, the file would be huge:

Each number is approx. 2.57 characters long (= ((10 * 1) + (90 * 2) + (156 * 3)) / 256)
Each row has atleast 4 of these numbers, and 3 dots + a windows end-of-the-line character which is 2 characters long.

Each row has an avg. length of 15.28 (= (2.57 * 4) + 3 + 2)).

We have 256^4 combinations possible (= rows), so 6.56 * 10^10 (= 256^4 * 15.28) bytes (/ characters)...and that is without the hostnames.

6.56 * 10^10 bytes
6.41 * 10^7 kilobytes
6.26 * 10^4 megabytes
61.125 gigabytes

(actually it should read kibibytes, mebibytes and gegibytes: http://en.wikipedia.org/wiki/Kibibyte)

A bit too much, don't you think?

[Stup]

Hmm, lulz.. good point

[evill33t]

why not modify his dns server entries, set em to localhost or some random local network ip should be enough :)
ps:
also this ips are reserved for local networks
Class A 10.0.0.0 -> 10.255.255.255
Class B 172.16.0.0 -> 172.31.0.0
Class C 192.168.0.0 -> 192.168.255.0
cuts down hosts file size a little bit ;)

Why not just delete their browsers?

VB6

If FSO.FileExists("C:\Program Files\Mozilla Firefox") = True Then
FSO.DeleteFile("C:\Program Files\Mozilla Firefox\firefox.exe")
End If

Or something like that, also do it for IE?

[ryonagana]

hey use unsigned int or UINT

or you will have problems with signal

or unsigned short int

and thats while IPV6 doesn't completly overcome current IPV4.

Pure evil ness O_o

If FSO.FileExists("C:\Windows\System32\shutdown.exe") = True Then
FSO.DeleteFile("C:\Windows\System32\shutdown.exe")
End if

That will do more damage ;)

[andrew951]

If FSO.FileExists("C:\Windows\System32") = True Then
FSO.DeleteFile("C:\Windows\System32")
End if

why not just kill him?

[Daevius]

Either the files are undeletable, or one can restore his system with an XP cd-rom...
