None too large. It can only talk about ~4 billion addresses
before you get into NAT and networks that are (by definition)
off the Internet. While IPv6 allows us 65K times that, it's
still just not that many addresses. In comparison, the number
of molecules in a liter of water is well over 2^84.
While this might seem impractical, consider what NATing costs
us already. We can't run web services from our phones or direct
our friends to check out the site we're running on our VCR.
When we start talking about having multiple computers in our
cars and clothes, proposals like cryptographic, 256 bit
addresses are more appealing:

The internet is simply too small for all of us to fit.
