* Create assignment objects in ARIN for your longer-prefixes based on 
customer and/or region with appropriate geographic info,

* Make sure your forward and reverse DNS are accurate -- I'm told some 
geo-location databases look at this if you put geographic info into your 
A(AAA) or PTR records, (e.g., blah.raleigh.nc.us.myfavoriteisp.net)

* Reach out to GeoIP DBs like MaxMind, IP2Location, etc. and submit updates.

Unfortunately, you may have to wait several weeks or even a month for 
databases to update.

C'est la vie.
