Third-party material

MAC address vendor data. Vendor names on the MAC address lookup come from the public MAC address assignment listings (MA-L, MA-M, MA-S and IAB) published by the IEEE Registration Authority, retrieved 2026-10-13. Only the assignment prefix and the registered organization name are used (no addresses); the data files are served from this site and the lookup runs in your browser. The listings are a snapshot: assignments made after that date are not included.

No other third-party libraries, fonts or data sets are used. Address rules follow the published RFCs named on each page.
