Re: Market-based address allocation

I guess the better question is, what changed between 1996 and 2003?

- Processor speeds have increased dramatically
- Memory is dirt cheap in a way almost unthinkable in 1996.

So, a little additional routing table bloat hurts no one. Yes, yes, this
is heresy.

Of course, that doesn't mean that a market based system causes ANY additional routing
table growth...

- Carriers have no incentive to change their filters

- The current length filters work quite nicely. /20s are always routable,
/24s are usually routable, depending on the weather, etc. YMMV, of course.

- ARIN, or whomever is the brokerage/dealmaker/clearinghouse for these
deals can simply refuse to transfer anything smaller than a /20, unless
its in legacy swamp space

- The sellers would, for their own protection, refuse to stipulate that
ANY block they sell is globally routable, if they have any sense.

- Of course, current, more or less unutilized class As and such might get
sold off in /20 chunks and advertised, but theres nothing wrong with this.

If, by a routing prefix market, you mean that folks with lots of prefixes
get to pay folks to carry their data, then its a DOA idea. Current
Settlement Free Peering arrangements work fine - no one is looking to
upset the apple cart.
