Just played around. Dunno if copilot used the correct format for dns objects but now i see it's better:
<address-book>
<name>global</name>
<address>
<name>ntp_server</name>
<dns-name>
<name>time.cloudflare.com</name>
</dns-name>
</address>
<address>
<name>admin_workstation</name>
<ip-prefix>172.16.0.100/32</ip-prefix>
</address>
<address>
<name>mgmt_subnet</name>
<ip-prefix>172.16.0.0/24</ip-prefix>
</address>
</address-book>

and now to something completely different - CCVS, CCAS, CCTE, CCCS, CCSM elite
