Sorry for my last post: I sent a draft mail instead of the corrected one. Let's go back to my own concern: dnsmasq and soa, if you don't mind. Here is my dnsmasq.conf file: resolv-file=/etc/dnsmasqresolv.conf
interface=eno1 interface=wlp3s0 no-dhcp-interface=enp2s0 auth-zone=rodary.net auth-soa=2018022800,root.ns.rodary.net,10800,3600,10800 dhcp-range=10.42.0.20,10.42.0.200,infinite As you guessed enp2s0 (eth0 now) is my INET interface. Shouldn't I add a "auth-peer=217.70.177.40" line for AXFR to ns6.gandi.net? With all my stupid previous acts, I don't dare to try it, specially when it could affect outside hosts e.g. my registrar.
