Yes. > or is this an issue with my DNS server? No, its an issue with the delegation of Ipswitch's IP address. The 156.in-addr.arpa. parent servers all report the following 21.156.in-addr.arpa. parent servers: auth01.ns.harvard.net. auth02.ns.harvard.net. hub.ipswitch.com. hub.ipswitch.com reports that 156.21.1.2 reverses to list.ipswitch.com. auth01.ns.harvard.net. and auth02.ns.harvard.net. reports that there is no PTR record for that IP address. So its a crap shoot depending on which 21.156.in-addr.arpa. parent server is queried. -- [EMAIL PROTECTED] "The avalanche has already started, it is too Rod Dorman late for the pebbles to vote."
