RE: IP Address

Maybe not ("Without having any context, it's really difficult to give the
"right" answer to the question.") but you gave a GREAT answer nonetheless

NSLOOKUP is a tool used to test DNS to make sure it's working correctly. 
The IP address that it shows when you just type NSLOOKUP and press ENTER 
is the IP address OF YOUR DEFAULT DNS SERVER.

While that MIGHT be the IP address of your iSeries, if you're running your 
own DNS server, it doesn't have to be. You can use DNS servers provided by 
your Internet Service Providers, or one that's running on another machine 
on your network, or whatever else you like.

There's also the possibility of running an iSeries without using DNS at 
all.  I don't recommend it, but you could run an TCP/IP-enabled iSeries 
that does everything by address rather than domain name.  Or, you could 
put everythin in your hosts table.  In those cases, there'd be no DNS 
server, so you'd get nowhere with NSLOOKUP.

Furthermore, NSLOOKUP is installed when the DNS server is -- so many 
people reading this thread won't even have an NSLOOKUP command on their 
systems.

Those who have said that the poster should use NETSTAT *IFC are absolutely 
correct. This tells you the IP address of each TCP/IP enabled network 
interface. One of the problems with the way that question was asked was 
that you don't assign an IP address to a "computer".  You assign an IP 
address to a "network interface". (Every system will have at least two IP 
addresses, and can have thousands of them, depending on how many network 
inferfaces it has.)

Of course, typing NETSTAT *IFC will only help you in an interactive 
application where you want to know your IP addresses.

Sometimes you're writing program that needs the IP address, and since 
there can be more than one, you need to know the CORRECT IP address for 
what you're doing.

Without having any context, it's really difficult to give the "right" 
answer to the question.
