I know that you've asked about using it live, but IMO, you should
reconsider.
Given the latency between the creation of a new OUI and it showing up in a
given environment, live scraping is significant overkill. Platforms like
Forescout pull it about once a quarter, IIRC.
Pulling the text file is also probably significantly more reliable than any
given web interface, as you've already discovered.
And if you cache the whole text file locally, there's no way that anyone
external to your organization -- even IEEE -- can tell which OUIs you are
looking up.
