We use private address space here for various things, some of which are even production, but you've never once seen us leak the advertisements for them. And if we did make the mistake of allowing them out, no one should ever listen to us about them. Blocking traffic from reserved space at your borders and not listening to route advertisements for reserved space should be common practice. I would hope anyone clueful enough to be on this list would know this already. -- Joseph Shaw - firstname.lastname@example.org NetAdmin/Security - Insync Internet Services Free UNIX advocate - "I hack, therefore I am."
