Dynamic DNS

    For years i’ve had dynamic DNS working on the domains us-west-2a.boxen.mage-net.net, us-west-2b.boxen.mage-net.net, us-west-2c.boxen.mage-net.net
    These are three t2.nano AWS Instances behind EBS I only need static IP for rsync. So AWS EIP is overkill.

    So Dynamic DNS.

    NS Master

    nsf.nuhosting.net.	300	IN	A	52.207.147.83

    Slave

    nsc.nuhosting.net.	300	IN	A	35.157.121.152
    nsg.nuhosting.net.	300	IN	A	52.56.40.202

    nsf.nuhosting.net.

    /etc/bind$ named -v BIND 9.10.3-P4-Ubuntu  

    nsg.nuhosting.net.

    /etc/bind$ named -v BIND 9.10.3-P4-Ubuntu  

    On nsf.nuhosting.net. I have

    zone "mage-net.net" { type master; file "zones/mage-net.net"; update-policy { grant ddns-key.mage-net.net zonesub nameservers; }; allow-transfer { nameservers; }; };

    nameservers
    On nsf.nuhosting.net is

    acl "nameservers"   { 52.207.147.83; 52.56.40.202; 35.157.121.152; 10.44.3.5; };

    If on nsg.nuhosting.net

    rndc retransfer mage-net.net

    I get…
