Ubuntu LoCo DNS nsset tool needs some Perl love

Recently I had to use the nsset commandline tool, which can be used to modify the DNS records of your Ubuntu LoCo (Local Community). The nsset tool can be found on the LoCo Teams DNS Admin wiki page in the attachments section. Just want to say that I really appreciate this tool and want to thank all contributors! I’ve discovered a bug (deprecation actually), which I can not fix. To be honest, I am a SysAdmin and not a programmer.
