It looks like the ISP hasn't set things up properly for your subnet.  They
created the CNAME records, and delegated the subdomain
0-15.200.54.216.in-addr.arpa, but to their own servers:

0-15			1D IN NS	ins1.iplt.twtelecom.net.
			1D IN NS	ins1.milw.twtelecom.net.

Those NS records should point to your servers, not theirs, unless they're
configured as slaves of your server.  And in that case they should still
include your servers as well, unless you're a hidden primary.

No.  You may be the only customer using that class C today, but what about
tomorrow?

And either way, the ISP has to delegate the reverse domain to your servers.
