It seems that, every so often, dnsmasq needs to be restarted - unless we blame
WIDE dhcpv6. Here, dnsmasq has been running for about a week, and a newly
dhcp6c[412]: dhcp6_get_options: get DHCP option identity association, len 18
dhcp6c[412]: IA_NA: ID=0, T1=0, T2=0
dhcp6c[412]: copyin_option: get DHCP option status code, len 2
dhcp6c[412]: status code: no addresses
dhcp6c[412]: get_ia: make an IA: NA-0
dhcp6c[412]: update_ia: status code for NA-0: no addresses
dhcp6c[412]: update_ia: IA NA-0 is invalidated
dhcp6c[412]: remove_ia: remove an IA: NA-0
Restarting dnsmasq always makes things work again, for awhile, and the client
dhcp6c[412]: dhcp6_get_options: get DHCP option identity association, len 40
dhcp6c[412]: IA_NA: ID=0, T1=1800, T2=3150
dhcp6c[412]: copyin_option: get DHCP option IA address, len 24
dhcp6c[412]: copyin_option: IA_NA address: 2604:dead:beef:cafe::01
pltime=3600 vltime=3600
dhcp6c[412]: dhcp6_get_options: get DHCP option status code, len 9
lapis dhcp6c[412]: status code: success
I've mentioned this on the mailing list from time to time, but no response yet.
If anyone has ideas about how to debug dnsmasq when it begins sending an empty
Nontemporary Address, please let me know.
Arch Linux
dnsmasq 2.76-4

It would be useful if you turned on the dnsmasq option --log-dhcp and
posted the contemporaneous logs from dnsmasq.

Cheers,

Simon.
