Maxmind delivers some dataset useful for geolocation:

GeoLite2 databases are free IP geolocation databases; The GeoLite2 Country and City databases are updated on the first Tuesday of each month. The GeoLite2 ASN database is updated every Tuesday.

IP Geolocation Usage

IP geolocation is inherently imprecise. Locations are often near the center of the population. Any location provided by a GeoIP database should not be used to identify a particular address or household.
Use the Accuracy Radius as an indication of geolocation accuracy for the latitude and longitude coordinates we return for an IP address. The actual location of the IP address is likely within the area defined by this radius and the latitude and longitude coordinates.

Includes city, region, country, latitude and longitude. This product doesn't contain any IP addresses.

Includes the following fields: ( Technical Details )

• Country Code
• ASCII City Name
• City Name
• Region
• Population
• Latitude (The approximate latitude of the postal code, city, subdivision or country associated with the IP address.*)
• Longitude (The approximate latitude of the postal code, city, subdivision or country associated with the IP address.*)

Another interseting dataset, even if no more mantained is World cities with population:

City/state/country text as it appears in source files is algorithmically matched against a master geocode file from Google and MaxMind open source files.
