RE: Growing from 256 to 2048 TLDs

["Marsh, Miles (Gene)" <MarshM at diebold.com>]

Jim,

Is it worth considering a method by which there could be more flexible
expansion of the number of potential TLD's?  I know the prevailing
thought is that we must put a stake in the ground, but any constraining
factor could have negative potential.

Thanks for the well written response. I will try to reply to
each of your points.

As you note, the following accommodates 256 TLDs.

	aaaaaTTT.TTTTTbbb.bbbbbbbb.bbbbbbbb

In the IPv8 Plan, we support 2,048 TLDs. That looks like...

	aaaaaTTT.TTTTTTTT.bbbbbbbb.bbbbbbbb

The extra bits get added to the right of the TTTTs...

Applying this to the scheme I suggested, each of the existing TLDs
in the initial group of 256 would be allowed to ADD 7 more TLDs at
some point in the future. This will bring the number to 2,048. Here
is more information as well as a list of the current IPv8 TLDs.
