[AusNOG] Telstra using US DOD IP's like they are RFC1918

[Ben Hohnke]

That site does state that those ranges aren't advertised publicly, and only
used internally - at lease I'm not receiving them on my feeds:
xxx-xxx-BDR01#sh ip bgp 30.0.0.0
% Network not in table
xxx-xxx-BDR01#sh ip bgp 30.0.0.0/8 longer-prefixes
xxx-xxx-BDR01#

Doesn't make it right, however I'm sure in a network of Telstra's scale,
RFC1918 exhaustion is would be an issue!
