Restrict dynamic updates to one domain - disallow subdomains

[André Steden]

Hello,

is it possible to restrict dynamic dns updates to one domain?

Allow this:

update add host1.example.de 86400 a 1.1.1.1
update add host2.example.de 86400 a 2.2.2.2

Deny this:

update add host1.subdomain1.example.de 86400 a 1.1.1.1
update add host2.anysubdomain.example.de 86400 a 2.2.2.2

What must i specify in the update-policy option for the example.de domain?

Regards, André
