I checked my historic files from 1991, 1997 and 1999 and don't see this block being allocated to anyone (don't have much data from 1991 - 1997 unfortunetly...). My guess is that this /16 was never allocated. On Wed, 28 Sep 2005, Edward Lewis wrote:

Isn't 172.15/16 legacy Sun example space pre 1918? It's all over CCO and Sunsolve in examples and defaults.
I poked some more and the LACNIC server says it is unallocated. That was the most straightforward answer of the bunch.
It's an interesting exercise to see what the 5 RIRs return and what IANA doesn't. ;)
ARIN - "no records found" APNIC - ' 172.0.0.0 is not allocated to APNIC' but lists CC of AU AFRINIC - '0/0', CC of EU LACNIC - "unallocated" RIPE - pretty much the same answer as AfriNIC IANA - doesn't query for numbers
Didn't see a WhoIs box on the NRO site.
