Hi ... I got to ask a question about public ip's. If I go and get a
block of ip's with an ISP. Will that mean that if I assign those block
of public ip's to any computer on the internet that machine will be
separately viewable!? ... Because I am using a cable modem attached to
a netgear router. If I get the router to assign my LAN the block of
public ip's they are not separately viewable from the internet. The ip
that I can view from the internet is the ip address of my cable modem.

I know I am doing something fundamentally wrong here.... cud some1
please cleariy this to me!

Thanks.

Why would you want to assign a series of public IP addresses to your
LAN?

No and Yes... Base on what you wrote it sounds like you want to use your
current cable connection as the gateway for your public ip's. The problem
is no one will know how to get to them since the cable company is not going
put those addresses into their routing tables. Even if you initiate the
contact (i.e. bring up yahoo.com from one of those servers/pc) the data
would not know how to get back. Secondly it hard to find an ISP that will
just hand out ip addresses unless you are a customer. With that said, there
are ways around it, but complicted and detailed.

thanx for your reply ... i see what you mean ... for some reason i
wasnt thinking straight probably .... for some reason i thought if a
public ip was assigned to a computer on the net then it wud be viewable
from there as well ... like to connect to it using that particular ip !
............i think i need to read more up about it ....... the ways
around it that you meantioned ... how complicated would they be !? ...
