Where 4291 fits
Why 4291 is special
A 128-bit address gives about 340 undecillion possibilities — enough to assign more addresses to every square millimetre of Earth than IPv4 had in total. The abundance is deliberate, to make address conservation unnecessary.

IPv6's address space is vastly larger than any projected need, specifically so that conservation measures like NAT become unnecessary. The waste is the feature.
