Hey Buck, dnsmasq blocks all IPv4 address replies in the "private" subnets when enabling stop-dns-rebind. For IPv6, it blocks only the IPv4-mapped address ranges matching said private subnets. Neither ULAs nor LLs (link-locals) are blocked in the IPv6 range. I agree this should be added. I

I am using dnsmasq version pi-hole-2.80 as embedded in Pi-hole, with my router set as its sole upstream server (server=192.168.178.1#53). When evaluating DNS rebind protection provided by dnsmasq (by adding stop-dns-rebind), I observed that dnsmasq correctly detects and suppresses IPv4
