You can do a whois search at arin.net to see the allocation.

172.0.0.0/12 is often confused with the private 172.16.0.0/12 address
space, which I would consider a 'scraping the bottom of the barrel'
allocation.

I also noticed a couple of subnets in that range showing up in the weekly
Cidr reports, beginning in July.
