[LDM #QZR-407100]: Reverse DNS and LDM

Hi John,

No worries.  In fact, I am currently kibitzing in the LDM training workshop
that is being held here in our offices in Boulder.

When you use 'IDD', are you referring to the North American Internet
Data Distribution system that we maintain, or are you referring to
your own data distribution system?  If the answer is the latter, then
you can setup your system using only IP addresses.

This does not resolve here at the UPC.  For instance, here is the output
of 'nslookup' here at UCAR:

% nslookup 67-20-79-154.leasingisp.com
Server:  laraine.unidata.ucar.edu
Address:  128.117.140.62

*** laraine.unidata.ucar.edu can't find 67-20-79-154.leasingisp.com: 
Non-existent host/domain

But, there is forward and reverse DNS for 67-20-79-154.hostmonster.com:

% nslookup 67.20.79.154
Server:  laraine.unidata.ucar.edu
Address:  128.117.140.62

Name:    67-20-79-154.hostmonster.com
Address:  67.20.79.154

% nslookup 67-20-79-154.hostmonster.com
Server:  laraine.unidata.ucar.edu
Address:  128.117.140.62

Non-authoritative answer:
Name:    67-20-79-154.hostmonster.com
Address:  67.20.79.154

67-20-79-154.hostmonster.com is resolvable; 67-20-79-154.leasingisp.com is not.

Again, we need to know if you are trying to set things up to work with
the IDD we manage, then having forward/reverse DNS is _highly_ desired.
If you are setting up your own relay network, it is useful, but not
mandatory.

Cheers,

Tom
