For the sake of argument, we'll assume that you've got proper SOA records for
these zones. 8^) A couple of points jump out:
You need both of the NS records for the duo-brugge.com. zone. The root servers
list both dns.duo.be. and secnds.eunet.be. as name servers for the zone, so
you need to have NS records for both of them. Also, if you want
mxrelay.eunet.be to handle mail for duo-brugge.com. as a back-up, you'll need
an MX record for it.
You can't have a CNAME with the same name as its zone. So the CNAME for
duo-brugge.com. is problematic and you should use an A for it instead. You
can, in general, use CNAMEs for other hosts, as appropriate, but if you're
going to be moving everything to a new subnet, you'll still need to go through
and change at least one A record for each zone that has a host name that's the
same as the zone name.
And, as someone else pointed out, don't forget the trailing dot (.) on all the
names.
