They help a little for the public who have zero operational experience, once you get to the sizes described here they provide no real benefit. 2,4,8 parallel delegations has never been hard for non nibble boundaries. It’s not like IPv4 where you get up to 128 parallel delegations for non octet boundaries. 0+1, 2+3, 4+5, 6+7, 8+9, a+b, c+d or e+f 0+1+2+3, 4+5+6+7, 8+9+a+b or c+d+e+f 0+1+2+3+4+5+6+7 or 8+9+a+b+c+d+e+f A /20 is 268435456 /48’s which is ~1/person in the US. > Furthermore, from a conservation perspective, a few /16 allocations pose > little difference compared to a slightly larger number of /20 allocations. > Also, all the RIR allocations above /24 make little difference from a > conservation perspective compared to the more significant number of > allocations between /32 and /24. > > I recognize that /16 allocations offend some people's sensibilities; I can > respect that, and they should support this policy.
