What are the differences between Geofeeds and Whois information?
LACNIC publishes information on IP assignments and sub-assignments through different means: Whois port 43, Bulkwhois, RDAP, delegation file and the dbase/lacnic.db.gz file (the result of policy LAC-2018-3). These can be queried to obtain information on organizations that have received IP addresses and their contacts. In all cases the geographic information (postal address, city, country) obtained from LACNIC might correspond to the city and country registered in the service agreement with LACNIC or to the client address stated by the member. However, this information might not match the actual location where the IP resources are being used.
This registry information is free and publicly available; for this reason, some organizations have been using it for IP geolocation purposes. However, the nature of this data means that location accuracy is low and this practice creates issues for customers, ISPs and content providers, among others.
Geofeeds is a free public tool that allows network operators in the region to explicitly state where their IP resources are being used, subdivide the blocks they have been allocated and specify location information for each sub-block detailing information such as country, region and city.
