What it is
GeoNames' list of populated places over 15,000 inhabitants with the IANA time zone of each, compiled into a grid the lookup searches for the nearest place inside the located country. It settles the zone for split countries and regions the curated map answers null for, within a distance cap, and only where the map could not.
What it answers
In the IP response this source feeds timezone, timezone_source. Every answer names the datasets it read in its sources block with the date each was synced, so the figure on this page and the one in an answer are the same figure.

A source names a network or an operator, never a person. An address inside one of these ranges tells you what the connection is — a cloud instance, a VPN exit, a gateway, a listed host — and nothing about who is behind it.
