Wifi Hotspot dnsmasq no DHCP ACK

I am creating a Wifi hotspot with hostapd and providing DHCP/DNS through dnsmasq on an Android 5.0.1 device. When a client connects to the Wifi hotspot it is subsequently unable to obtain an IP address through DHCP. The dnsmasq server claims to send a DHCP ACK response but no packet is seen in wireshark. dnsmasq is started with the following options (formatted for viewing). /system/bin/dnsmasq --keep-in-foreground --no-resolv --no-poll --dhcp-authoritative --dhcp-option-force=43,ANDROID_METERED --pid-file --dhcp-range=2001::2, 2001::10, ra-stateless,infinite --enable-ra --dhcp-range=192.168.42.2,192.168.42.254,1h --dhcp-range=192.168.43.2,192.168.43.254,1h --dhcp-range=192.168.44.2,192.168.44.254,1h --dhcp-range=192.168.45.2,192.168.45.254,1h --dhcp-range=192.168.46.2,192.168.46.254,1h --dhcp-range=192.168.47.2,192.168.47.254,1h --dhcp-range=192.168.48.2,192.168.48.254,1h --dhcp-range=192.168.49.2,192.168.49.254,1h The dnsmasq logs show that dnsmasq receives the DHCP REQUEST from the client and attempts to respond with DHCP ACK.

Instead, the host is issuing ARP requests for the offered IP address. I cannot understand why the host is sending ARP requests for the offered IP address instead of sending the DHCP ACK. Can anyone help me understand what I am seeing and how it can be fixed? Thanks. **EDIT** The wifi hotspot was created by monitoring all commands sent to the netd socket during standard wifi hotspot creation through Android and replaying those commands with /system/bin/ndc. ndc netd softap fwreload wlan0 AP ndc netd softap set wlan0 Redskins wpa2-psk DanSnyderSucks ndc netd softap startap ndc netd interface getcfg wlan0 ndc netd interface setcfg wlan0 192.168.43.1 24 up multicast running broadcast ndc netd tether interface add wlan0 ndc netd interface getcfg wlan0 ndc netd network interface add local wlan0 ndc netd network route add local wlan0 192.168.43.0/24 ndc netd ipfwd enable ndc netd tether start 192.168.42.2 192.168.42.254 192.168.43.2 192.168.43.254 192.168.44.2 192.168.44.254 192.168.45.2 192.168.45.254 192.168.46.2 192.168.46.254 192.168.47.2 192.168.47.254 192.168.48.2 192.168.48.254 192.168.49.2 192.168.49.254 ndc netd tether dns set 501 8.8.8.8 8.8.4.4 ndc netd nat enable wlan0 rmnet0 1 192.168.43.0/24 ndc netd tether ra true wlan0 rmnet0 **EDIT** Any suggestions or ideas on where to even begin debugging would be greatly appreciated. I have tried comparing logcat logs and kmsg logs but I have been unable to exact any useful information.
