よくあるご質問

What is IP address geolocation?

IP geolocation is the process of identifying the approximate location (such as country, city, or approximate latitude/longitude) of a device (laptop, phone, server, etc.) based on its IP address. It helps identify where internet users or servers are connecting from, often used for content customization, market research, security, or compliance.

How does IP geolocation work?

IP geolocation works by mapping IP addresses to geographic locations using large geolocation databases compiled from various sources. These sources include:

• Regional Internet Registries (RIRs): They assign IP netblocks to internet service providers (ISPs) and organizations, often with associated location data.
• ISP and network infrastructure data: Helps identify where IP addresses are used.
• Wi-Fi and mobile data: Cross-referenced when users connect to known networks or cell towers.
• Traceroute and latency measurements: Used to estimate location by analyzing how data travels across networks.

The result is an approximate location—often down to the city level—but accuracy can vary depending on the IP type and the methods used.

How do you identify geolocations of domains or email addresses?

To identify geolocation for a domain, we run a DNS lookup to identify its associated IP address, and then we run IP geolocation for that address.

For email addresses, we first discover the mail server that this email uses based on the MX record of the domain in the email. Then, we run a DNS lookup for that server to get its IP, and then, we can geolocate it.

Does an IP geo lookup identify the precise location?

No, IP geolocation does not identify a precise location like a street address. It typically estimates a general area—such as a city or region—and its accuracy depends on factors like the type of IP address (static vs. dynamic), ISP data, proxy usage, VPNs, etc.

Is IP geolocation a privacy concern?

No, it’s not. IP address geolocation often reveals the location of the website user’s internet service provider (ISP), which has allocated the IP address the user is using.

This means that it can offer city-level precision, but not down to the street level. It doesn't reveal any personally identifiable information, meaning that when a website is using IP geolocation, it doesn’t create privacy concerns for the website users. It also means that using IP geolocation doesn’t require any explicit permission from the user.

How accurate is your IP geolocation information?

WhoisXML API provides accurate IP geolocation data, with the location accuracy being limited by the fact that IP geolocation doesn’t offer street-level accuracy by design.

The accuracy of IP geolocation data is sufficient for geotargeting or geofencing, as well as for cybersecurity purposes and market research.

What can I use IP geolocation data for?

There are applications of IP geolocation data across very different industries and use cases. Here are some examples:

• Ecommerce: Redirect the user to the local website or show prices in local currency.
• Digital advertising: Deliver geo-targeted ads to the website visitors.
• Cybersecurity: Flag or block login attempts from unexpected locations.
• Online banking: Request multi-factor authentication when logging in from a new location.
• Streaming services: Enforce licensing restrictions by blocking access to certain media based on the user's country.
• Online gaming: Match players from the same region to reduce latency.

These are just a few example use cases. Almost every industry has its own use case for IP location data.
