I think so...


root at dc3.mydomain.com ~ $ (screen) samba-tool dns query dc3 mydomain.com @ ALL
   Name=, Records=5, Children=0
     SOA: serial=620, refresh=900, retry=600, expire=86400, minttl=0, ns=dc3.mydomain.com., email=hostmaster.mydomain.com. (flags=600000f0, serial=620, ttl=3600)
     NS: dc3.mydomain.com. (flags=600000f0, serial=110, ttl=900)
     NS: dc4.mydomain.com. (flags=600000f0, serial=110, ttl=900)
     A: 192.168.0.218 (flags=600000f0, serial=110, ttl=900)
     A: 192.168.0.219 (flags=600000f0, serial=110, ttl=900)
