[Dnsmasq-discuss] iPhone 17 Pro Max DHCP not working
Brian Mattey via Dnsmasq-discuss · 2025-12-06 · via dnsmasq-discuss
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.
