What should the ip address represent in a standard ppp connection from a home pc to the ISP?

I just recently helped a woman not able to get on the internet. I
checked all her networking settings and they appeared to be right, but
when I tried to get on the internet, meaning I typed www.msn.com or
something else, the status bar flashes that it is looking the name up
on 127.0.0.1 and then it gives me the page not found eror.
From there I do a ping and a tracert to google.com or msn.com and they
Click to expand...
each give me a valid return which means the connection is still active
but when I try it in the browser it won't work.

Finally I do ipconfig and it tells me the ip address is the same as the
gateway. Should this be the case? When the computer doesn't know
where to find the page it needs, it is supposed to look at the gateway
and ask the question of the gateway machine specified by it's ip
address in the gateway box. (Someone please correct me if I'm wrong?)
What I was looking at appears to me that the computer was programmed to
look at itself when it couldn't find the page it needed.

anyway I played around a little more and just when I was about to leave
I hungup the modem and then reestablished a connection manually to her
ISP without usiong all the extra software, and it worked. I still
don't know why it wasn't working before. I'm hoping someone has had a
similar problem.
 
This is typical of a browser hijack. Try running the latest version of
"hijack this". Also, check (in add/remove programs) for "newdotnet" or other
suspects (AVG will report newdotnet as a virus). You need to uninstall it
from add/remove, don't let an adware program do it.

To clear up some of the things you asked about:
When you try to go to a website, either in your browser or ping, tracert,
etc from the commandline using a name (google.com), the computer first looks
at the local HOSTS file (which is pretty much deprecated now), then assuming
you don't have a local WINS server, as such:

First it will go about resolving the name to an IP address. Since you
provided a Fully Qualified Domain Name, or "FQDN" (google.com), it will look
to DNS. The local router may well be the DNS server, or rather a DNS proxy.
This is very common on broadband and cable routers. Once the name has been
resolved to it's IP address it will attempt to locate the host. If it is a
local address (in the same subnet as the IP settings on the network card),
it will do a broadcast for the MAC address of the computer with that IP
address (ARP). If it is not, it will send the request to a router (usually
the default gateway). The default gateway router will pass it on to it's own
default gateway router and so forth until it finally reaches the router that
is directly connected to the subnet where the destination IP address resides
(Amazing, ain't it?).

Since your browser is trying to resolve names using 127.0.0.1 (her
computer), its probably because some spyware proxy software is installed on
her computer, forwarding DNS requests to a server that tracks her IP address
and the sites she visits. If it isn't working anymore (the site is down or
adware removal software killed it but didn't fix the problem), you could be
in for some fun trying to get it to work. Look on the web for "Winsock
Fixer". It's a free download that will set all of your TCP/IP socket
settings to factory (Do the stuff at the top first).

thanks Kurt. This is good info. I needed to know the specific process
for finding anything on a network or the net.

I appreciate your help. feel free to drop me a line should you have any
questions from me also. As for the client, she doesn,t want to pay me
and swears it was never working everytime I leave so I'm not coming
back unless, but this is good info so I can figure out network settings.
