ouidb-json

JSON (and raw) version of the IEEE OUI database, published from http://standards-oui.ieee.org/oui/oui.txt.

It is updated every night by ouidb-to-json-publisher, which only commits when the upstream IEEE data actually changes.

Published files

File	Description
ouidb.json	The OUI database parsed and converted to JSON
ouidb.json.gz / ouidb.json.bz2	Compressed variants of ouidb.json
oui.txt	The raw IEEE oui.txt, mirrored verbatim
oui.txt.gz / oui.txt.bz2	Compressed variants of oui.txt
ouidb.schema.json	JSON Schema describing ouidb.json

This repo also acts as a mirror of the raw oui.txt. The IEEE host sits behind an anti-bot WAF that blocks many datacenter / cloud IP ranges (the connection is dropped before HTTP), so downloading oui.txt directly often fails from CI runners and cloud servers. If that happens to you, fetch it from here instead.
