# Dynamic IP address

Glossary · Identification

Canonical page: https://datasdk.ai/glossary/dynamic-ip-address

A dynamic IP address can change as a network provider assigns addresses over time.

## Why it matters

Treat a match as a time-specific signal rather than permanent identity.

## Illustrative example

A connection may receive a different address after reconnecting.

## What to check

Old address-to-company information can become inaccurate.

## How Data SDK fits

Data SDK connects website visits with available company details worldwide, from startups to larger businesses. Coverage and fields vary. Start free trial opens an email request; terms are confirmed with the team. The full API is coming soon.

These are suggested workflows, not a list of built-in integrations. Use your own approved analytics, CRM, and research process where needed. Matches and fields vary. A company match does not identify a person or prove buying intent.
