Re: [address-policy-wg] "Dirty" recycled network assigned

[David Conrad <david.conrad@localhost]

An "interesting" (in sort of the way the Ebola virus is "interesting")
problem that is going to become much more common as we start reallocating
previously allocated or otherwise flagged blocks.  Leo Vegoda has done a
couple of presentations on this.

Just imagine the fun folks who are going to get prefixes out of 1.0.0.0/8
are going to have.

Options I can think of:

1) Get everybody to transition to IPv6 (um, yeah).
2) Get all the folks who are running RBLs/DUNs to update their lists when
address status changes (slightly more realistic than (1)).
3) Get everybody to use reputation services like
http://www.karmasphere.com/, et al. (no, I'm not affiliated with them)
4) Get RPKI deployed to reduce the need for black list services (um, yeah.)
5) Get the folks who win the draw on prefixes to go around to every black
list service themselves (as they discover them) and convince the operator of
that list (somehow) to remove them (the default).

No good answers I'm aware of...
