Hi folks,
Thank you for the reply.
Unfortunately, I did not understand how I am supposed to add multiple A-records for the same name to the zone-file to fix this issue.
On my Bind9 server, I have the following zone-files:
- - -
forward.example.lan.db:
$TTL 604800@ IN SOA ns1.example.lan. hostmaster.example.lan. ( 1 ; Serial 604800 ; Refresh 86400 ; Retry 2419200 ; Expire 604800 ) ; Negative Cache TTL
@ IN NS ns1.example.lan.
ns1 IN A 192.168.0.10ns1 IN AAAA fe80::f21f:afff:fe5d:be90
- - -
reverse.example.lan.db:
$TTL 604800@ IN SOA example.lan. root.example.lan. ( 1 ; Serial 604800 ; Refresh 86400 ; Retry 2419200 ; Expire 604800 ) ; Negative Cache TTL
@ IN NS ns1.example.lan.10 IN PTR ns1.example.lan.
- - -
Please, advise.

Another option would be to leverage BIND's ability to sort A records
based on configured preference (in the config file, not the zone file)
based on client IP. So even if BIND does return the Docker IP, it's not
the 1st IP in the response, thereby hopefully alleviating the problems
of it's existence.
This may be germane if the Docker IP is automatically registered and
making it stop will be a different kettle of fish to roll up a different
hill.
