Hmmm, probably something to do with your "reverse" naming convention:

host 67.196.137.1
1.137.196.67.in-addr.arpa domain name pointer 
H1.C137.B196.A67.tor.colo.heavycomputing.ca.

host 67.196.137.163
163.137.196.67.in-addr.arpa domain name pointer sizone.org.

host 67.196.137.16
16.137.196.67.in-addr.arpa domain name pointer 
H16.C137.B196.A67.tor.colo.heavycomputing.ca.

host 67.196.137.162
162.137.196.67.in-addr.arpa domain name pointer 
H162.C137.B196.A67.tor.colo.heavycomputing.ca.

IP 67.196.137.163 appears to actually have a "name" and everything
else has Hnnn.C137.B196.A67.tor.colo.heavycomputing.ca (where nnn
is the fourth octet IP).
