I want to show country flag depending on ip address I receive at server side. Are fixed ip addresses are assigned to countries ? Where can I get database for ip address to country mapping ?
回答1:
Take a look at the following:
- IP address geolocation SQL database
- Geo Locate IP Address XML API Whois Map Country Provider
- How to Geolocate Visitors Using an IP-to-Country Database
- Free IP to Country Database
- My IP Address Lookup and Geotarget IP Project
- MaxMind - Open Source IP Address to Country Database
- IP address geolocation SQL database
Also on Stack Overflow:
- What is the most applicable solution to detect which country an ip belongs to?
- Is there any possible way to find the name of the country using IP with scripting language PHP?
- IP to Country?
- code for finding the state,country,city from the IP Adress in php
Once you have the country code, then you can display the flag with these free icon sets which use ISO country codes:
- Flag icons
- Flags of the World
PHP Advent also just published a whole article on a very similar process:
- GeoIP Wrangling

You're looking for an IP geolocation service such as MaxMind.
回答3:
ip2location.com provides an IP range database which can be used to tag IP addresses
they provide it in different formats as well so you can choose which one is useful to you

Maxmind is the one we use
回答5:
Open Sourced self contained flag rendering based on IP: ip2ensign
It will lookup UV coordinates in a flag texture atlas that matches an arbitrary IP. And it comes with the IP range database and the texture.
