Removing dynamic DNS entries

Use update delete command in nsupdate. If you specify an IP address, just that record will be deleted, otherwise all records of the given type will be deleted.

Delete all:

netmanager 1# host laptop1
laptop1.school.internal has address 10.0.117.44
laptop1.school.internal has address 10.36.0.238
netmanager 2# nsupdate
> update delete laptop1.school.internal IN A
> send
> quit
netmanager 3# host laptop1
Host laptop1 not found: 3(NXDOMAIN)
netmanager 4#

Delete one IP address:

netmanager 1# host laptop1
laptop1.school.internal has address 10.0.117.44
laptop1.school.internal has address 10.36.0.238
netmanager 2# nsupdate
> update delete laptop1.school.internal IN A 10.36.0.238
> send
> quit
netmanager 3# host laptop1
laptop1.school.internal has address 10.0.117.44
netmanager 4#

Manually adding dynamic DNS entries

Adding entries is similar, but you must specify the time-to-live (TTL) value:

netmanager 1# nsupdate
> update add testdns.school.internal 3600 IN A 10.0.123.123
> send
> quit
netmanager 2# host testdns
testdns.school.internal has address 10.0.123.123
