RE: Map APPC LU name to an internet address

Is there an order for the as400 to look up host info like an Microsoft OS?
Meaning if I have the as400 set to "*remote" under "CFGTCP" option 12, will
it look in its "host" file too?
Thanks for the info so far,
Doug

In this example you would end up with

RALYAS4B.USIBMRA.SNA.IBM.COM

So, in option 10 of CFGTCP, you would add that URL to the IP address of your
machine. As someone else said, the first 2 items can be found with DSPNETA.
of the machine to which you will connect. Use local location and local net
ID. You also need an entry for the machine you are on. The first element is
usually the name of your iSereis, the second element is APPN by default.

I would use the hosts entry first, to see that it works. Then take it out of
the hosts table and put it into a DNS and see what happens. If it works,
cool! If not, go back to the hosts table - have not heard whether SNA looks
at the actual HOSTS file (it's actually QATOCHOSTS or something) or uses
name resolution.

Now, using the hosts table for this is different, in my view, than the usual
use of hosts tables. The purpose of these very specific URLs is a mapping
for AnyNet only. It may be that you do not want everyone in the enterprise
to have access through DNS to these IP addresses. And you may want to limit
the machines which can be connected with AnyNet - a DNS would make everyone
known, I tihnk, unless there is some filtering possible.
