[Samba] How to delete an unwanted NS record

[James B. Byrne]

I have this on the DC smb4-1.brockley.harte-lyne.ca:

samba-tool dns query localhost brockley.harte-lyne.ca brockley.harte-lyne.ca
ALL -U administrator
Password for [BROCKLEY\administrator]:
  Name=, Records=6, Children=0
    SOA: serial=7, refresh=900, retry=600, expire=86400, minttl=3600,
ns=SMB4-1.brockley.harte-lyne.ca., email=support.harte-lyne.ca.
(flags=600000f0, serial=110, ttl=3600)
    NS: SMB4-1.brockley.harte-lyne.ca. (flags=600000f0, serial=110, ttl=900)
    NS: smb4-2.brockley.harte-lyne.ca. (flags=600000f0, serial=110, ttl=900)
    A: 192.168.18.161 (flags=600000f0, serial=110, ttl=900)
    A: 192.168.18.162 (flags=600000f0, serial=110, ttl=900)
    A: 192.168.216.162 (flags=600000f0, serial=110, ttl=900)
  Name=_msdcs, Records=0, Children=0
  Name=_sites, Records=0, Children=1
  Name=_tcp, Records=0, Children=4
  Name=_udp, Records=0, Children=2
  Name=DomainDnsZones, Records=0, Children=2
  Name=ForestDnsZones, Records=0, Children=2
  Name=smb4-1, Records=1, Children=0
    A: 192.168.18.161 (flags=f0, serial=110, ttl=900)
  Name=SMB4-2, Records=2, Children=0
    A: 192.168.18.162 (flags=f0, serial=110, ttl=900)
    A: 192.168.216.162 (flags=f0, serial=110, ttl=900)

192.168.216.162 is an aliased IP on 192.168.18.162 which points to
smb4-2.internal.harte-lyne.ca.

host -t A smb4-2.internal.harte-lyne.ca
smb4-2.internal.harte-lyne.ca has address 192.168.216.162

host -t PTR 192.168.216.162
162.216.168.192.in-addr.arpa domain name pointer smb4-2.internal.harte-lyne.ca.

I can get rid of the A record, at least temporarily, with:

samba-tool dns delete localhost brockley.harte-lyne.ca smb4-2 A 192.168.216.162
-U administrator
Password for [BROCKLEY\administrator]:
Record deleted successfully


How do I get rid of the 192.168.216.162 NS record while leaving 192.168.18.162?
 I cannot determine the correct syntax for the 'samba-tool dns delete' command.
