After a guest DHCP IP move, the split-horizon resolver kept serving the old IP: the drop-in (address=/domain/ip) updated but 'systemctl reload dnsmasq' (SIGHUP) does NOT re-read /etc/dnsmasq.d config — only /etc/hosts + cache. Changed reload() -> restartDnsmasq() so address= changes actually take effect. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
