Note, ARIN is an RIR, a regional internet registry, which is what I
presume you meant there.  Nevertheless, while it might be worth a try
from a research perspective, it may be a bit risky in a production
environment. In addition, someone may announce a more specific so keep
that scenario in mind.  The CIDR Report monitors RIR allocation data.
This may be of interest to you:

You can get access to that allocation data as noted here:
