It's typical...but not contained within the "looks sort of like 1918 
space" networks.  Do enough network support and you'll run into similar 
stuff from time to time.  Fortunately, the damage is limited to the idiots 
using IPs picked from their (or worse, they're overpaid/underqualified 
consultants) asses not being able to reach the actual assignees of those 
spaces.
