Please, someone, make them stop telling that bullshit.
Only the first half of IPv6 address contains routing information. Okay, some routers may accept even /128 routes, but that's non-standard and one should not depend on that — the subnet is always /64.
So, the proper address space increase comparsion should be: 0000:0000:0000:0001:: vs 0.0.0.1, i.e. 2^64 vs 2^32.
