Building on what LocutusofBorg said: <extremely evil grin>
Currently, the internet uses
IPv4 technology, which allows for 2^32 nodes to be connected to the internet (assuming no network address translation is being done), which amounts to
4, 294, 967, 296 possible nodes. In spoken word terms, that is four
billion, two hundred and ninety-four
million, nine hundred and sixty-seven
thousand, two hundred and ninety-six possible nodes.
The new technology,
IPv6, allows for significantly more nodes to be connected simultaneously. Specifically, 2^128 nodes will be possible, which amounts to
340, 282, 366, 920, 938, 463, 463, 374, 607, 431, 768, 211, 456 possible nodes. In spoken words, that is a whopping three hundred and fourty
undecillion, two hundred and eighty-two
decillion, three hundred and sixty-six
nonillion, nine hundred and twenty
octillion, nine hundred and thirty-eight
septillion, four hundred and sixty-three
sextillion, four hundred and sixty-three
quintillion, three hundred and seventy-four
quadrillion, six hundred and seven
trillion, four hundred and thirty-one
billion, seven hundred and sixty-eight
million, two hundred and eleven
thousand, four hundred and fifty-six nodes.
And it gets better.
MD5 hashing technology also has 2^128 possible hashes. however, the newer standard, SHA1, has more still - 2^140 to be exact, which amounts to (are you sitting down?)
1, 393, 796, 574, 908, 163, 946, 345, 982, 392, 040, 522, 594, 123, 776 possible hashes or, in spoken words, one
tredecillion, three hundred and ninety-three
duodecillion, seven hundred and ninety-six
undecillion, five hundred and seventy-four
decillion, nine hundred and eight
nonillion, one hundred and sixty-three
octillion, nine hundred and fourty-six
septillion, three hundred and fourty-five
sextillion, nine hundred and eighty-two
quintillion, three hundred and ninety-two
quadrillion, fourty
trillion, five hundred and twenty-two
billion, five hundred and ninety-four
million, one hundred and twenty-three
thousand, seven hundred and seventy-six.
And it gets better still.
Public-key cryptography uses larger numbers still - 2^1024 or more is common. That amounts to (OK, this is getting rediculous)
