How is it possible that http://1089059683 takes me to Google.com ? there's no TLD!

[ober]

Is it possible that 1089059683 is the IP without the periods?

[448191]

Yes it's odd. I'm able to ping it from the command line too, so it's not passing through google. Only thing I can think of: it's registered with the root name servers (like the TLD's).

It resolves to this IP: 64.233.187.99

Which is indeed a google IP:

just out of curiosity, how did you come about this? entering in a random number and poof, it just so happened to be google?

[neoform]

I was just sitting in my parents basement typing http://1 .. http://2 .. http://3 ... http://4 .. until i got to http://1089059683 and poof, there was google! go figure.

[ober]

.... that's a very odd thing to be doing.... and how long did that take you?

[redbullmarky]

i can't remember the details, but i remember seeing somewhere that typing a 'long' IP in the address bar will resolve just like a domain name/IP would.

if you do this:

Code: [Select]

<?php
echo long2ip(1089059683);
?>

you get: 64.233.187.99, which also takes you straight to Google.

[neoform]

I just figured it out.

window's TCP/IP stack does a special conversion on integers..  that's actually Google's IP address 64.233.160.0 converted to an INT(10)

Here's the PHP code for encoding/decoding an IP address so you can test it yourself..  you can access any website that way..

PHPfreaks.com = http://1113697029 (doesn't work though, apache no likey that url, heh)

Code: [Select]

function ip_encode($ip)
{
    if ($ip == '')
        return 0;
    else
    {
$ips = split ("\.", $ip);
return ($ips[3] + $ips[2] * 256 + $ips[1] * 256 * 256 + $ips[0] * 256 * 256 * 256);
    }
}
function ip_decode($int)
{
    if ($int == '')
        return 0;
    else
    {
$w = (int)(($int / 16777216) - 256 * floor(($int / 16777216) / 256));
$x = (int)(($int / 65536) - 256 * floor(($int / 65536) / 256));
$y = (int)(($int / 256) - 256 * floor(($int / 256) / 256));
$z = (int)(($int) - 256 * floor(($int) / 256));
return ($w.'.'.$x.'.'.$y.'.'.$z);
    }
}

http://0x4261ab05/ - oooooh magic

More magic:
http://0x40E9A763 = http://1089054563 = http://64.233.167.99 = http://google.com

The magic formula:

o_n is an octet

Example IP: 64.233.167.99
o₁ = 64
o₂ = 233
o₃ = 167
o₄ = 99

Formula:

And surprisingly enough that gives 1089054563.

This is just an IP in DWORD format (a dotless IP).
-----------------------------------

Code: [Select]

<a href='http://phpfreaks.com@0xd8a38903'>PHP Freaks</a>PHP Freaks (click at your own risk)

An unaware user could click the link and get to another site than they thought (URL obfuscation). It could be improved with a little JavaScript:

Code: [Select]

<a href='http://phpfreaks.com@0xd8a38903' onmouseover="window.status='http://phpfreaks.com'; return true" onmouseout="window.status=''">PHP Freaks</a>
Beware where you click (if your browser doesn't warn you about that there is a username in the url).

Can we quit with the math already? I'm getting chills..

Well, it's not Windows, it appears to be IE. None of the above examples will work in FF for me.

I am interested in how you came up with that url.

Not true, it should.

Also try "ping 0x40E9A763" from the command line.

The're all just numbers mathematical (hexademal, octal) equal to an IP. Don't ask me for an in depth explanation though, I suck at math. Ask Daniel, he seems to be a mathhead.

Exactly how likely is that? Mathhead! 

[obsidian]

Not true, it should.

It might should, but the fact is, it doesn't. I've tried multiple times, and I'm getting the good ol' "Unable to connect" error:

Firefox can't establish a connection to the server at 0x4261ab05.

I've tried it with every link provided in this thread, too.
