How to describe 2^128, the total number of IPv6 addresses

I like the way described on Wiki about 2¹²⁸, the total number of IPv6 addresses:

... approximately 5×10²⁸ (roughly 2⁹⁵) addresses for each of the roughly 6.5 billion (6.5×10⁹) people alive in 2006. ...

You will get a share of "astronomical" number of addresses in IPv6: 5×10²⁸. I believe it is impressive enough for us all to imagine how large the number is!

I also found an interesting page questioning the correctness of some bold statements about this number, such as "IPv6 will let us individually address every proton on earth" or "the number of possible IPv6 addresses will be larger than the number of molecules in the universe".

I think this analysis is correct, so I won't use such statements anymore!
