My preferred mechanism is the basic text registry file [1] followed by cmd-f or grep.

I wish this text file had a last-updated-date in it.

Just recently we had a OUI chip which was being used in one of our boards, which was throwing off our post-production automated tests. Turns out the vendor added a new OUI, but didn't update all the references to its datasheets on their website. Took us a while to figure out what the problem was.

Maybe "Last-Modified" header combined with "ETag" would be good enough alternative?

I happened to run across this yesterday, and it looks nice. However, it would be nice if it could accept different common formats so they don’t need manual editing, such as having - as a separator instead of :.

I use https://www.wireshark.org/tools/oui-lookup.html exactly because of that reason.

It does, doesn't it? Best I can tell, it does care at all what formatting symbols you use or don't use.

I have a tool to generate plausible-but-random MAC addresses that align to the vendor of your choice.

I got tired of Cableco, Inc. tech support identifying my router by mac address and ultimately them telling me to reboot/replace/reset my router rather than troubleshoot the actual issue.

So, I set my router's mac address to something that matched an ancient IBM mainframe. Fun conversations ensued.

how were you able to change mac, are you in the US?

I thought DOCSIS modems have disabled this function in the US

Specifically, the DOCSIS cable modem was rented from the cable company and it was reporting the CPE MAC address that it sees connected to it. In this case, it was reporting the MAC address of my router and the CSR on the phone would look up the brand of the router to provide specific instructions on how to reboot/reset.

I'd love to know more about the fun conversations. Did you blog on this?

alyandon3• 3 years ago

Unfortunately, no. The typical interaction was the CSR requesting that I waste a bunch of time logging into the router, verifying a bunch of settings and requesting that I reboot the thing before continuing to troubleshoot my problem. They'd never take my word for it that I had already verified things before calling in so it was a complete waste of my time.

By changing the MAC address of my router, the CSR would generally pause in the middle of their script and ask me what brand router I had. I would tell them I wasn't sure but it was a really big box and said IBM on the side and then they'd give up and continue to the next phase of troubleshooting.

I'm a terrible person.

Is this any better than the Wireshark database? https://www.wireshark.org/tools/oui-lookup.html

This is just another website that monetizes freely available information.

Fun fact - the NSA oui prefix is 00:20:91

Sorry, but a MAC address page doesn't need cookies, nor cloudflareinsights.com, nor buysellads.net, nor carbonads.{com,net}, nor a completely ridiculous amount of Javascript.

There are plenty of better sites to use, such as Wireshark's:
