I was speaking about in general residential use. Yes, large companies
may proxy behind a single IP, but in the general sense for residential
customers, not likely.

In WHAT case?
If my IP were visible in my headers, it would be MY IP, not some
"server". richard does not understand what a 'server' is.

Really? So, you mean to tell me that if ALL IP's were visible in
headers, and I posted to usenet, there's a HIGH chance that someone
coming here a few minutes later posting to this same group would have
the IP I just had? Bullshit. You're as dumb as bullis.

Riiight.

I understand how IP assignment works. And if you believe bullis
understands anything, you're a bigger troll than he is.
Not to shoot down your hero, but let me give you a good laugh.

"As you may know, I have been touring the country side for the past
two
years. I stay at various motels and get online using their wifi
system.
Assume for the moment that the motel has 100 rooms. 100 guests all
have computers and all are connected to the system.
Assuming again, that all are connected to the same news service that
posts an IP in the headers. All 100 post to the same thread in the
same time frame of say 10 minutes. With none having lost a connection
so their IP would not change for that reason.
Now tell us, we the world, sir, exactly how many users will have a
different IP?
Now do recall smartboy, that the ISP knows only that the motel is
connected. Which is connected via hard wired cable. The ISP gives the
motel a constant static IP. ONE IP.
Let us assume again, that 100 people in the same motel are surfing the
net. Each machine is surfing a different website. Now how is that
possible with only 1 IP?
I'm sure that you are also well aware that an ISP is usually assigned
a block of IP's Now I know you know what an octet is so with the
combination of the last two octets, that gives a possible 65,000 IPs.
Yet, the ISP has 500,000 customers. 200,000 are online right now.
You say, one machine, one IP. Please explain then how the ISP can
handle this situation."
Read the whole thread. It's hysterical.
