Well, you could have run this on a DC:

samba-tool dns --help

and from the output, you could have thought about running this:

samba-tool dns delete --help

Which would have got you this:

Usage: samba-tool dns delete <server> <zone> <name> <A|AAAA|PTR|CNAME|NS|MX|SRV|TXT> <data>

So using your data:

samba-tool dns delete 127.0.0.1 mydomain.com @ A 192.168.0.208
