There are a few things that should be taken into consideration when dealing with your problem.

First, the OUI used by the netaddr 1.3.0 package is outdated.

I have an iPhone 16 with' OUI 0C-85-E1. You can check directly in IEEE or here that it is a valid OUI, but it's not updated in the netaddr source.

You can solve this problem using another approach to get OUI info from the web.

maco = src_mac[:8].upper().replace(":", "-")
try:
  response = requests.get(f"https://api.macvendors.com/{oui}")
  if response.status_code == 200:
    macf = response.text
  else:
    macf = "Not available"
except Exception as e:
  macf = "Not available"

But here there's the second problem. Apple uses a private Wi-Fi addresses security functionality that prevents from showing the real OUI on all requests, including probe requests.

Check here when this option is off:

And when it's on:

You can check that OUI 6E-BA-4F it's invalid.

Android has a similar function too. So you will have the same problem.

If your clients use this function there is no way to determine the vendor based on OUI from probe requests.
