thats as specific as you will get unless you some how figure out how to scam access to and spider the current registration lists and filter for registered corporate addresses.
Found a source for known IP blocks for Ohio. Hoping that someone has their own list also, to compare, merge and use.
I believe the Maxmind paid DB goes down to city level. GeoIP is never going to be 100% accurate, especially once you're narrowing it down to a relatively small region. It's probably paid because there are staff manually deciphering that the hostname ip1.2.3.4-nyc.provider.com is probably in New York City... but according to WHOIS the administrative contact details for that block are on the other side of the USA.
The location data is in the Free GeoLite2-City-CSV_20150106 at Maxmind -- some assembly required ;)
I think you can do some free lookups if you are just backtracking at Maxmind.
Wasn't all in vain -- nice to know that current US zip code and other countries postal codes data is available on an updated basis for another project of mine ...

Thank you all for the additional resources. Sent the details you shared over. The zip code data is something of a bonus also, which I asked my guy to look into for another project. So an extra thank you!!!
