What Is DNS and How Does It Work – A Comprehensive Guide I propose to create a Docker Bind9 Image using base Docker Alpine Linux images, with S6 init system.

The main router must be set to forward packets! The ability to forward packets must be set / allowed, edit or add the following parameters in sudo vim /etc/sysctl.conf:

• net.ipv4.ip_forward = 1
• net.ipv4.conf.all.proxy_arp = 1
• sudo sysctl net.ipv6.conf.all.forwarding=1 similar for ipv6

After applying these changes reboot or apply setting using sudo sysctl -p /etc/sysctl.conf

• /usr/sbin/named -f -4 to start the isc-bind9 application called named,
  • -f to run in foreground
  • -4 to run ipv4 only
• rndc stop to stop named - need to implement this in S6
• rndc reload to reload the named configuration files
• named-checkconf /etc/bind/named.conf
• named-checkzone kptree.net /etc/bind/db.kptree.net
• named-checkzone 1.168.192.in-addr.arpa /etc/bind/db.1.168.192
• cat /log/named/bind.log to list bind log file
• From Listing all zones loaded in BIND
  • rndc dumpdb -zones
  • cat /var/bind/named_dump.db to see the database dump
  • named-checkconf -l does this option still exist?
  • named-checkconf -p for a flatened uncomment listing of the configuration files
