Q:

Homebrew installed: geoiplookup shows no output - howto install GeoIP-data?

> geoipupdate; geoiplookup 8.8.4.4
> echo $?
0

It does not print any output. According this posting there should be GeoIP-data. Howto use that on macOS?
> brew search geoip
geoip                                                                                                                                geoipupdate
homebrew/nginx/geoip2-nginx-module    homebrew/php/php53-geoip              homebrew/php/php54-geoip              homebrew/php/php55-geoip              homebrew/php/php56-geoip              homebrew/php/php70-geoip              homebrew/php/php71-geoip

I wish to use local Geo data, not query an external web hosted API.

A:

After installing geoipupdate and geoip with geoipupdate support navigate to the file /usr/local/Cellar/geoipupdate/2.3.1/etc/GeoIP.conf and open it.
Replace:
# Please see http://dev.maxmind.com/geoip/geoipupdate/ for instructions
# on setting up geoipupdate, including information on how to download a
# pre-filled GeoIP.conf file.

# Enter your user ID and license key below. These are available from
# https://www.maxmind.com/en/my_license_key. If you are only using free
# GeoLite databases, you make leave the 0 values.
UserId 0
LicenseKey 000000000000

# Enter the product IDs of the databases you would like to update.
# Multiple product IDs are separated by spaces.
ProductIds GeoLite2-Country GeoLite2-City
...

with:
# The following UserId and LicenseKey are required placeholders:
UserId 999999
LicenseKey 000000000000

# Include one or more of the following ProductIds:
# * GeoLite2-City - GeoLite 2 City
# * GeoLite2-Country - GeoLite2 Country
# * GeoLite-Legacy-IPv6-City - GeoLite Legacy IPv6 City
# * GeoLite-Legacy-IPv6-Country - GeoLite Legacy IPv6 Country
# * 506 - GeoLite Legacy Country
# * 517 - GeoLite Legacy ASN
# * 533 - GeoLite Legacy City
ProductIds GeoLite2-City GeoLite2-Country GeoLite-Legacy-IPv6-City GeoLite-Legacy-IPv6-Country 506 517 533
...

and update the database with geoipupdate.
Entering geoiplookup 8.8.4.4 now will yield:
GeoIP Country Edition: US, United States
GeoIP City Edition, Rev 1: US, N/A, N/A, N/A, N/A, 37.750999, -97.821999, 0, 0

Update:
According to adejones' comment the GeoIP.conf file moved to /usr/local/etc/GeoIP.conf in newer versions of "brew-installed" geoipupdate.
