Device identification
Identification is a display hint, not an authenticated fingerprint. A saved manual device type takes precedence. Specific hostname or custom-name clues come next, followed by a small set of vendor hints and the default group. Names and types never affect routing, firewall rules or DHCP configuration.
Short English words require token boundaries. A generic switch means a
network switch; nintendo-switch means a console. gateway means a router,
and Cambridge-PC means a computer. Chinese device keywords are also accepted.
The previous broad OUI tables had no recorded provenance. They were replaced
with the 13 documented entries in oui-hints.json. Manufacturer assignments
were checked against the Wireshark project's automatically generated
manufacturer data,
which incorporates IEEE registration data. The verification source checksum
is recorded with the entries. Only assignment facts are retained; the complete
database is not bundled.
A manufacturer assignment identifies an organization, not a product. Apple, Google, HP and other vendors with diverse products therefore have no automatic device type hint. Ubiquiti and H3C use the general network-device category; Espressif and Lumi use the general smart-home category. These remain guesses, and users can override them. Locally administered or randomized MAC addresses never use vendor hints. Hostname and manual identification still work for them.
