[AusNOG] [Fwd: [bogon-announce] IANA IPv4 allocations and bogon update 1/8 and 27/8]

[Matthew Moyle-Croft]

I've had my /24 (an historic 192/8 range) used by someone on their internal network for some obscure reason.  So I was getting my DSL connection at home DoS'ed by some of their internal machines trying to talk to something when they decommissioned a site.  Eventually tracked them down and got it stopped!  At least they were nice about doing it.

The internet is a big and crazy place.  If you can think of something stupid then someone has written a white paper justifying why it's a good idea and a thousand corporate drones have implemented it faithfully like Lemmings off a cliff (*).

I've never hear of or run into this anywhere in the world, FWIW.  Unallocated netblocks should never be used for such purposes due to the disruption caused when they're finally allocated, as is this case in this instance.

I inherited a network which we partitioned off from a big giant network who shall remain unnamed (starts with a V and ends with an N ;-) who used 113.52.0.0/16 for Hawaii on boxes that should not have to reach the outside world (but some do via NAT).  That was allocated to APNIC.  Luckily the boxes don't need to reach the areas 113.52.0.0/16 was allocated to.  Yet.  So it definitely happens...
