how to fix incorrect GeoIP data?

[cra at WPI.EDU (Chuck Anderson)]

I have a customer who received a new assignment from ARIN, but the 
GeoIP data is returning Canada rather than the US as the location of 
the IP prefix.  Google redirects to www.google.ca and some other sites 
aren't working correctly because they expect a US IP.  Does anyone 
have any advice on how to update the GeoIP and other similar 
databases?

Thanks.
