<font face="Arial, Helvetica, sans-serif"><span style="font-size:12px">I have set up two virtual machines on a virtual local network using Oracle VirtualBox. One machine is a DNS authoritative-only server. </span></font><font face="Arial, Helvetica, sans-serif"><span style="font-size:12px">The zone is named "reseau1.lan" and defined only in bind9 zone files. If I really have to, I will name it "reseau1.home.arpa" according to RFC 8375. (I chose .lan inspired by RFC 6762 appendix G). The IP address of the DNS server is 172.16.0.254 and the IP address of pc1 is 172.16.0.21.</span></font><br>
