Your ISP is probably an entrpreneur who, if you read D&B very
carefully, now knows less about DNS than you.  They do not even have
the reverse DNS domains for their own IP addresses delegated from
APNIC.  So of course, they can't delegate them; so of course, nobody
has ever asked them.

At least, so I think, from my cursory glance at the records on the
'Net.

nslookup -type=ns 164.32.108.202.in-addr.arpa.
*** No address information is available for "164.32.108.202.in-addr.arpa."

nslookup -type=ns 32.108.202.in-addr.arpa.
*** No address information is available for "32.108.202.in-addr.arpa."

nslookup -type=ns 108.202.in-addr.arpa.
Non-authoritative answer:
108.202.in-addr.arpa	nameserver = svc00.apnic.net
108.202.in-addr.arpa	nameserver = ns.apnic.net
