s/sending a DNS query to the MAC address/sending an ARP request to the MAC address/
Actually, while this LWN sentence was confusingly brief, the original post *was* talking about DNS queries. ARP on the LAN will just get you the LAN IP address. John's original post was suggesting:
  • Get victim's wifi MAC address (which can be correlated with location by one of the companies that surveil this)
  • Connect to the open wifi (which will often let DNS through even if it's a captive portal)
  • Send a DNS request for attacker.com, which tells attacker.com's nameservers the victim's public IP address (if no intermediate DNS servers are used).
Now you've correlated victim's public IP address with location.

Oh geez, it's Jon quoting John. This is what happens when I post before waking up. If there had been only one, I would have not noticed, but when my brain saw a second one, it went off the rails.
