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…
