Of course we filter -


What is your requirement to do that? I am serious, because those are the
things the current draft is trying to document. If it is not covered by the
current text, please send details.


There are obvious reasons for filtering as Bob Austin pointed out last night/this
morning (time-differentiated threads when you are wrapped-around is a nightmare :-) )


Our reasons are the typical ones - mostly protecting from various features in M$
software. An important point is that there are few hosts which are *only* local.
In my experience a local-only host (eg a database-server part of a N-tier application)
are comparatively rare. Using locally scoped addresses for those is just more work
than putting the damned thing behind a firewall and filtering everything.


Currently the largest set of locally scoped hosts in my network are phones. This is
in itself a major pain since I am unable to deploy sip-to-the edge to these phones
and consequently I am in the process of getting globally scoped addresses for these
hosts.


Right now I cannot find a single application where locally scoped addresses give
me anything worth the effort. Those are my 5 cents - since you asked for details :-)


Cheers Leif
