Akamai Geolocation Secret Sauce?

[rvandolson at esri.com (Ray Van Dolson)]

Anyone familiar with how Akamai does its geolocation?  Presumably they
do more than Maxmind/WHOIS, but I suppose one or both of those could
factor in?

For those of you with ARIN IP space, do you typically SWIP things to
yourself to help clarify the locations where the IP space physically
resides to feed into Geolocation databases?

Thanks,
