[Dnsmasq-discuss] iPhone 17 Pro Max DHCP not working

[Brian Mattey]

Hi,

I have a new iPhone 17 Pro Max and it is not successfully DHCPing with dnsmasq 

I have tried 2.62 on an old Raspberry Pi 2, and 2.75 and 2.76 on a newer Pi 4.

I have been using dnsmasq on the old Pi for many, many years without any problems and with many different clients.  iPhones, Android Phones, assorted tables, windows, linux and so on.

With the new iPhone 17 looking at the log (with verbose DHCP logging turned on) I see it make a request and then the responses and then it just tries again and again and never gets an address etc.

What I see in the log is as follows and noting this is no different to an iPhone 15 that works OK.
