WorldIP - IP Geolocation, Internet Research

Opera browser users are able to go online through a special proxy server of the Opera. Also, Opera Mini mobile customers use these servers.

Of course, IP addresses belong to these servers, but they send header "X-Forwarded-For" with the real IP address of the user.

The list of Opera's proxies is helpful to determine the real country.

XX is our code, the total value of which is "unknown". It includes:
- the empty or unallocated space,
- distributed, but unused networks,
- internal and test networks (10.0.0.0/8, 127.0.0.0/8, etc.),
- anycast (as an example - Google's DNS server 8.8.8.8),
- the recently announced, but not yet distributed on the internet networks.

There is no detailed information about the location of routers in API database, (we see it as unnecessary for "normal" user). Instead the region (e.g.: EU, AP) or the country of global operator (e.g.: CA for Tata) will be displayed.

In firewall it is possible to filter by country. It is very useful to block certain countries or to balance the requests to different backends, each of which handles its region.

Now WorldIP database exists in the format for geoip module from the extension package xtables-addons for iptables. Using this module, you can build more flexible rules for iptables, based on IP-geolocation.

WorldIP differs from similar databases in about 30% of the used IP address space.
This is because they mostly use whois-data, without regard to real use of networks.
An example: the network of Kodak 192.232.64.0 - 192.232.127.255.
Other databases show the USA for the entire network, but in reality it consists of the following subnets:

Thanks to Craig MacKenna, there is the module IP::World for WorldIP base in CPAN.
Today it is the fastest module for access to IP database. At Athlon64 2.4GHz are 236K req/sec; XEON E5405 2Ghz - 267K req/sec

WIP-tools include pings, traceroutes and Reverse DNS. Pings can be performed simultaneously on all servers. This option for traces will be available soon. Use our monitoring servers to analyse the IP addresses and networks.

Of all the Service-Codes, we have opened the satellite providers and bots (except spy bots) now, according to our classification it is 10-14 and 40-41.
Others will be opened some time later.

The access to databases with service codes is made possible only through API, they are not distributed in any other way. If it did, it would have no particular usage, since, for example, the renewal of proxy list and of Tor network active nodes occurs every hour anew.

There is a geolocation mod for Invision Power Board (IPB).

Configuration and use of the database (CIDR) are very practical and comfortable in nginx, so there is no problem to install it

The table worldip contains fields start, end and code. Every row means a network. start and end are integer fields with IP numbers, code is a double-character country code, like "US".
You can convert every IP address to IP number with following formula

You can leave your suggestions, ideas, critical remarks or other comments either in this topic or using the contact form. We will try to answer your questions promptly, but it might take a short while.
For correction of erroneous geographic data you can use the special form on our website.

Whois contains information such as geographic locations of network owners, and not the geographic location of networks themselves. But these data are also often inaccurate, sometimes even intentionally erroneous.
Here are only a few cases with examples as disadvantages of such information.

WorldIP Free Geolocation Database

WorldIP Database helps determine exact geographic locations of Internet users based on their IP address. It supports all types of IP addresses and networks, including satellite networks. It is completely free for personal and business use, but we will be very glad, if you include a link back to WIPmania.com on your website.
The database is available for immediate download in any of the following formats
