Server locations & GEO IP databases

Gerhard Kleewein Updated by Gerhard Kleewein

At EDIS, we place a high value on correctly GEO localizing our services.

Each of the services EDIS provides are hosted exactly at the specified server location and connected to the Internet via multiple upstream providers and Internet Exchanges (IX).

Where is the GEO IP information stored?

The information at which geographic location an IP address is hosted, is primarily provided by the network coordination centres which assign IP addresses. For Europe, the Middle East and parts of Central Asia, RIPE NCC (Réseaux IP Européens Network Coordination Centre) is responsible for the corresponding database entries.

In addition, there are the following bodies with responsibility for the regions given in brackets: AFRINIC (Africa), ARIN (North America/USA), APNIC (Asia Pacific) and LACNIC (Latin America and Caribbean).

WHOIS databases

So-called WHOIS databases are operated by the above network coordination centers, in which the owners of an IP address range (service operators), contacts in the event of misuse, as well as corresponding GEO information - where an IP address range is announced, at which address, longitude and latitude - are stored.

this could look like this:

inetnum: -
netname: EDIS-HK-NET
descr: EDIS Infrastructure in Hong Kong
remarks: Central, Hong Kong
country: HK
geoloc: 22.2793278 114.1628131

What is Geolocation?

Geolocation refers to any kind of data that allows for determining, with reasonable precision, the location of a person or a device on planet Earth

Ever more, ever faster - ever more accurate?

Due to the need for more and more accurate data and even faster query options for a subscriber's GEO data using APIs, there has been a proliferation of Geolocation lookup providers. Some of them obtain their data (at least the basic material) from the reference databases of the network coordination centers RIPE, ARIN, APNIC, LACNIC and AFRINIC. Some of them let end users make changes to GeoIP address assignments. This leads to chaotic quality of the material in their databases.

Commercial Lookup Providers

Most query/lookup providers do have commercial interest. Request-limits are used to persuade users to buy enterprise subscriptions. Some providers allow free access to (older) databases in order to persuade potential leads to purchase enterprise material with accurate data. Some service-operators are not aware that they are checking their subscribers against old GEOIP database material. Some service providers find and use old GEO databases somewhere on the web and use this data for production with the same effect.

EDIS GEOIP data feeds

As mentioned at the beginning of this document, EDIS places a high value on correctly GEO located IPv4 and IPv6 addresses, respectively correctly geolocated services. For that reason, EDIS IPv4 and IPv6 GEOIP data-feeds have been made available to numerous lookup providers, so that they can obtain first-hand information regarding potential amendments.

EDIS works with the following renowned services and provides them with GEOIP data-feeds.
