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

[Steve Lisson]

Unfortunately it is more common that what might think, there has been
some discussion on Nanog regarding it (including comments like 'Most
ISP's, if not all, null route 1.0.0.0/8 therefore you shouldn't
encounter any problems using it in a private network.' and taking from
Wikipedia:

http://en.wikipedia.org/wiki/Private_network

Private use of other reserved addresses

Several other address ranges, in addition to the official private
ranges, are reserved for other or future uses, including 1.0.0.0/8 and
2.0.0.0/8[1]. Though discouraged, some enterprises have begun to use
this address space internally for interconnecting private networks to
eliminate the chance of address conflicts when using standards-based
private ranges.[citation needed]

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.

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...

Yeah I had some random small business, which if I recall was a telstra
managed router service.. anyway.. I don't recall which range but it was
something like 100/8 was in use for the entire network.. and their other
site (connected via VPN) used 101 or some other entire /8... complaint
was "I can't get to site X".. wonder why ;)
