Thank you for everyone's assistance. I have updated the zone files.
After the updates and restarting BIND, I run "dig +trace ptr
170.3.187.64.in-addr.arpa" and the result stops just prior to getting to
my DNS server and correctly resolving the name of the IP address. I'm
new to dig and do not know whether this is correct for an RFC2317 zone
delegation or whether the trace should be completing at my servers and
resolving the name. My guess is there must be something still incorrect
on my end.
Though, using NSLOOKUP against opendns servers for
170.3.187.64.in-addr.arpa does resolve the name correctly.
NAMED.CONF has the zone defined as follows:
zone "162-27.3.187.64.in-addr.arpa" IN {
type master;
file "64_187_3_162-27.rev";
};
The zone file looks as follows:
$ORIGIN .
$TTL 86400 ; 1 day
162-27.3.187.64.in-addr.arpa. IN SOA ns1.blue-dot.ca.
dnsadmin.ns1.blue-dot.ca. (
2009051202 ; serial
1800 ; refresh (30 minutes)
900 ; retry (15 minutes)
604800 ; expire (1 week)
1800 ; minimum (30 minutes)
)
NS ns1.blue-dot.ca.
NS ns2.blue-dot.ca.
NS ns3.blue-dot.ca.
$ORIGIN 162-27.3.187.64.in-addr.arpa.
170 PTR smtp3.netcraftcommunications.com.
