pilotgi,
Glad you made it. Pinging to get a numerical IP address is pretty straightforward; for instance to ping this site, you type in shell or terminal:
ping
www.linuxquestions.org
To ping the Suse Chicago server, you type:
ping mirror.mcs.anl.gov
When pinging, you don't have to precede with "http://" or "ftp://." There're even three other commands which are better than "ping":
host mirror.mcs.anl.gov (this command is fastest and easiest)
or
nslookup mirror.mcs.anl.gov
or
dig mirror.mcs.anl.gov
