Questions about Reverse Lookup Zone file!

[Marc C Storck]

Your Network Address is 65.119.31.32
Your Broadcast Address is 65.119.31.63 !!!!!!! not 62

What do you call reverse ping?

Please ask the Hostmaster of svl-ans-01.inet.qwest.net and
dca-ans-01.inet.qwest.net which is the responsible nameservers for
31.119.65.in-addr.arpa

to set the following in the zone file for 31.119.65.in-addr.arpa

32-63.31.119.65.in-addr.arpa.    IN    NS    ns1.sceptre.com.
32-63.31.119.65.in-addr.arpa.    IN    NS    ns2.sceptre.com. or whatever
your second nameserver is called.... you should have 2 but 1 is still fine
but REALLY NOT recommended

32.31.119.65.in-addr.arpa.    IN    CNAME 32.32-63.31.119.65.in-addr.arpa.
33.31.119.65.in-addr.arpa.    IN    CNAME 33.32-63.31.119.65.in-addr.arpa.
...
63.31.119.65.in-addr.arpa.    IN    CNAME 63.32-63.31.119.65.in-addr.arpa.


than create

a zone file for 32-63.31.119.65.in-addr.arpa

and add the following:

$TTL 43200
@ IN SOA ns1.sceptre.com. hostmaster.ns1.sceptre.com. (
2002050302 ; serial
1H ; refresh
15 ; retry
14D ; expire
12H ; default_ttl
)
@ IN NS ns1.sceptre.com.
57 IN PTR ns1.sceptre.com.
42 IN PTR www.sceptre.com.

This is described in a RFC, but I don't know which....

Best Regards,

Marc
