nsupdate delete question

Hi- While invoking nsupdate within a program I notice that trying to delete a nonexistant host does not return an error. Same thing seems to happen from the command line which I will show next.. [r...@mandy4 ccadns]# nslookup mandy11.example.com Server: 204.62.134.38 Address:204.62

lookup cnames

[r...@mandy4 ccadns]# rpm -qa|grep bind bind-utils-9.3.2-7.4.20060mlcs4 bind-9.3.2-7.4.20060mlcs4 I've tried but cannot find an option to return cname records for a given host. I did find dig and host command options that allows entering a cname with the result being the host that owns that cname.
