That's what DNS is for Skeeve.

I read this when it came out.  While I understand exactly what Jeff is saying, I personally don't agree with his approach.

I personally would like to see something else happen.... and I know this is far out, but here goes.

I'd like to see individuals to be able to get a /48 themselves... for it to be 'theirs' that they can take to ANY ISP they like (or more than one) and get announced.  They could keep it for life in theory.

I see that it could be like a cell/mobile number... port it, move it around, use it on your cell phone or anything you like... imaging wandering into a cell store and saying 'use this /64 please for my handset'.

There is enough /48's to do that for the entire planet, squillions of times over.... so why not?  Well, obviously BGP technology would have to change just a little bit ;-)  But I am sure it could be done.

THEN, ISPs wouldn't even need that much space themselves if every business and individual had their own space for all their own devices ;-)

BOOM! Mind blown.

Correct.

A /22 of IPv4 is equal to a /32 IPv6.  So you get up to a /32 of v6 for no extra fee.

BUT... If you are a business, expect only a /48...  If you are a Service Provider, you can probably justify a /32.

but seriously... a /48 is a TONNE for a business.  The only reason you'd want more is if you have multiple networks in geographic  disparate locations with different upstreams.

Jeff Doyle begged to differ on this a little while back:

TL;DR version:

 *   Businesses: allocate a /48 for every building, no matter how small.
 *   ISPs: allocate a /48 for every residential customer.
 *   Consistency is much more important than waste management.
