Answers to Common Questions about IP Geolocation 

What Is IP Geolocation?

Geolocation is the process of estimating or identifying the real-world locations of devices and their users worldwide. These devices can be mobile phones, computers, or radar sources. While geolocation has been around for a while now, it was only after the rise of smartphones and applications like Google Maps that we realized how powerful this data can be.

What Is an IP Address?

An Internet Protocol (IP) address is a unique numerical label assigned to each device that is part of a computer network that uses the Internet. It serves two primary functions—identifying a device on a network and providing a location for that device.

Two versions of IP addresses are commonly used. These are:

  • Internet Protocol version 4 (IPv4): It uses a 32-bit address scheme, allowing for a total of 2^32 addresses to exist. An IPv4 address is typically split into four chunks split by periods, such as
  • Internet Protocol version 6 (IPv6): Due to the Internet’s growth and the depletion of available IPv4 addresses, IPv6 was developed to allow for many more addresses. It uses a 128-bit address scheme. An example of an IPv6 address is 1200:0000:AB00:1234:0000:2552:7777:1313.

What Is IP Geolocation Data?

IP geolocation data refers to information about the physical location of an Internet-connected device based on its IP address. This data can help determine the country, region, city, and possibly even the ZIP code the device is in.

What Is an IP Geolocation Database?

An IP geolocation database is a massive repository of IP geolocation data. It’s frequently built by third-party providers who consistently retrieve anonymous IP data from various Internet service providers (ISPs) via legal agreements and other sources. The database can hold millions of records, which are regularly updated and made available for download in different formats.

How Is IP Geolocation Data Collected?

IP geolocation data collection is often done with the help of software that retrieve information from various sources, including:

  • Regional Internet registries (RIRs): RIRs allocate significant pools of IP addresses to ISPs and manage their corresponding records. These nonprofit organizations include the American Registry for Internet Numbers (ARIN) and the Asia-Pacific Network Information Centre (APNIC).
  • ISPs: They provide Internet access in specific regions, generally offering services to companies and individuals. They typically receive a block of IP addresses from an RIR, which they can then assign to customers.
  • City code interpretations: These are the naming conventions usually assigned to cities, providing clues about where connected devices can be found. They are often used by IP geolocation services to estimate a device’s location.
  • Domain data: Domain data lets organizations keep track of the owner of a selected range of IP addresses along with their corresponding postal addresses. This information can be part of an IP netblocks database or a WHOIS database that contains the contact and registration details of a target domain name and its corresponding IP addresses.
  • Browser geolocation: This data is gathered when users agree to share their location while browsing the Web to receive more targeted digital content.

Inability to access contentInaccurate IP geolocation data may restrict subscriber access to geography-specific content even if they are in the correct physical location.
Inferior user experienceIncorrect insights based on flawed IP geolocation details can result in irrelevant offerings or the use of the wrong language or currency on sites.
Poorly targeted marketing effortsOffers pushed to the wrong people due to inaccurate IP geolocation details can lead to wasted marketing resources and lost conversion opportunities.
Bad decision-makingSome organizations work with IP geolocation data to decide where to put up their server infrastructure or which providers to use. Unreliable information may cause bad decision-making, which can then result in substandard performance.
Erroneous attributionServices that keep track of online events may fail to correctly attribute user locations, resulting in misleading assumptions and observations.

Considerations When Looking for the Right IP Geolocation Data Sources

In light of the prevalence of data inaccuracy, here are some aspects to pay attention to when choosing a data source to geolocate IP addresses.

  • Accuracy claims: Accuracy varies between IP geolocation providers and databases, so it’s critical to check on claims made and see how services compare at a country, state, or city level. As a rule of thumb, accuracy on the city level is usually lower than the state or country level since the former requires much higher precision.
  • Coverage: It’s also important to look at the IP address space for a given location and check the percentage of routable addresses different providers cover.
  • Update frequency: Some data sources are updated daily, while others less frequently. Choose a source that updates data as frequently as needed.
  • Pricing: IP geolocation data sources can come free of charge or cost hundreds or thousands of dollars a month. Choose a data source that fits your budget and needs.


IP geolocation offers various benefits for companies in different industries. Websites can create tailor-made content based on where their users are. Marketers will be able to gain deeper insights for their strategies. With geolocation intelligence’s help, cybersecurity teams can quickly learn more about threat sources and network traffic. Keeping tabs on malicious entities may also be easier for law enforcement authorities. Finally, branding professionals can safeguard their intellectual property better and protect against piracy.
