DNS IP numbers should be in the TCP/IP control panel.  Typically they are 
automatically assigned along with your IP number when your dial in.  Since you're 
running an older OS I'm not sure exactly what it looks like.  It's been a few years 
since I was using that old of an OS with dial-up.  In the newer OSs you can manually 
enter the DNS IP numbers even if your own IP number is being automatically assigned by 
the PPP dial-up server.

As far as pinging goes, look for a program called MacPing or WhatRoute.  If you can 
ping the IP number but not the name then it's a DNS problem.  For example, here I've 
fired up MacPing and entered www.apple.com.  It resolved to IP number 17.112.152.32.  
That's what the DNS does.  It converted the name to the IP number.  BTW, the 
152.11.243.108 is my Mac's IP number but don't try pining that as I'm behind a 
firewall and it won't get through.

Source: [152.11.243.108] --> Destination: www.apple.com [17.112.152.32]
RESULT     
PKT#     TIME     LENGTH
success      1        5         56
success      2        5    
     56
success      3        5         56
success      4        5         56
success  
    5        5         56
Packets out/in/bad/%loss = 5/5/0/0
Round Trip Time (Ticks) 
min/avg/max = 5/5/5
~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Now I ping the IP number of www.apple.com.


Source: [152.11.243.108] --> Destination: [17.112.152.32]
RESULT     PKT#     TIME    
 LENGTH
success      1        6         56
success      2        5         56
success  
    3        5         56
success      4        5         56
success      5        5   
      56
Packets out/in/bad/%loss = 5/5/0/0
Round Trip Time (Ticks) min/avg/max = 
5/5/6
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
That too works.  I'm guessing that in your case when you ping apple's IP number it 
will work but when you ping www.apple.com it won't because your DNS is not working.  
It's not able to resolve what www.apple.com is.  If you use WhatRoute you'll have even 
more options to play with including a trace route, query, and whois functions.  But 
MacPing is simple and quick.  I can email it to you if you don't already have it or 
can't locate it.  It's a very small program.
