Further discussion would be useful on one issue that was brought to our
attention.
The issue is the status of 128.66.0.0/16. This block, TEST-B, has been
used for example purposes. There is no RFC that talks about this block,
but my understanding is that IANA/ARIN have marked it as reserved. If
you search the Internet you will find at least some number of examples
and firewall rule sets that use this block, but I have no good idea
about how widespread such usage is.
What should we do about this block? Some of the potential answers
include documenting its role, marking it as reserved but deprecating its
use in examples, and returning it to the free pool immediately (with a
warning sign about possible filtering problems).
