Glossary: IP Address

An IP address is a numerical label assigned to a device connected to a network, commonly used in analytics to approximate a visitor’s geographic location or to help distinguish unique visitors. Because IP addresses can be considered personal data, many privacy-first analytics tools anonymize or avoid storing them.

Examples

• A visitor’s IP address is used to estimate their country for a geographic traffic breakdown.

• An analytics tool truncates or hashes IP addresses to reduce privacy risk.

• A team uses IP address patterns, alongside other signals, to help filter out bot traffic.

FAQs

Is an IP address personal data?

It can be. Whether an IP address relates to an identifiable person depends on context and available means of identification; under GDPR, online identifiers may qualify as personal data. Requirements vary by jurisdiction.

How is IP address used in fraud detection?

Unusual patterns, like many accounts sharing one IP, can be a signal used alongside other heuristics for bot or Sybil detection.

Can an IP address identify a visitor?

An IP address can contribute to identifying a visitor when combined with other information, but may identify a network, proxy, or shared connection rather than one person. Treat it as contextual data and apply appropriate minimization and access controls.
