Whether you've found an incorrect vendor mapping, want to suggest a feature, have a question about how the tool works, or need to reach us about privacy or advertising — we'd like to hear from you.
We aim to reply within a few business days. Vendor-data corrections may take longer if they require rebuilding from the upstream IEEE registry.
Vendor assignments come from the public IEEE registry and other public sources. If a result looks wrong, it may be because the address is locally administered (no registered vendor exists) or sits in an unassigned block — our About page explains how the lookup works.
