Re: [Tm-rid] RAA/HDA - drawing the line in 32 bits

["Card, Stu" <[e-mail]>]

I'm fond of a simple 16 + 16 with the understanding that a single RRA
operator might be granted more than 1 value, enabling finer distinctions
than simply jurisdiction, e.g. if the US FAA were such an operator, it
could use 1 RRA value for Government HDAs & another for commercial HDAs.

For reference:
How many TLDs exist?
How domain name registrars?
How many domain name registry operators?
How many IEEE OUIs exist?
How many distinct organizations hold OUIs?
