and to think all I was going to say was that it's apparent
that he hasn't read the "How To Do Networking" book yet.
I've had enough of your insults, fella. Do me a favor and just
ignore what I post.
Most people mention IP Addy don't tell you whether they're
talking about the WAN IP or the LAN IP as they ass-u-me that
you can figure out which one they're talking about by the
context of the sentence or paragraph. Most ISPs assign
"dynamically" an WAN IP to their clients but all the machines
on the LAN when sending messages & stuff out to the Internet
[WAN] have the same WAN IP address. No matter which machine on
my LAN that I send a message to this list from will have the
same WAN IP address but you will not see the LAN IP address
thereby increasing security slightly. Only slightly in many
cases because the machine name is still in the email message
header.
I was setting up Internet access back when you could get a Class
C network (specifically 198.170.x) for an organization and it
(the organization) served as its own ISP for the organization's
computers, and all we had were hierarchies of routers and
computers. And every computer was ON the Internet -- part of the
WAN, so-to-speak! There was no DHCP and no WAN IPs and certainly
nothing like cable modems and DSL modems!
And I was also doing networking for individual PCs with a
telephone modem using -- darn, can't remember it's name but I
believe it was an interface for Windows sockets.
So shoot me if I haven't kept up. And yes, I cannot tell from
context what IP address a person is referring to when they say
that several PCs can have the same IP address.
Diane does some things differently primarily because she runs
server software that requires a separate, unique WAN IP
address. For example many FTP server apps require a unique WAN
IP address [but not all] so if I wanted to run an FTP server
app & say a Sharepoint server for Office collaboration I might
want 2 or 3 unique WAN IP addies. There are also ways around
some of this stuff like using a service such as DynDNS.org &
TZO.com but you probably ought to read the next book in the
series before you get into that stuff.
My local cable companies charges $20 for a static WAN IP & if
you want or need any add'l static WAN IP addies you're going
to pay thru the nose because they don't want anyone running a
server on their network. If you were a business on their
network & required more than 1 static WAN IP then you have to
call their 800 # as they don't publish those prices on their
website. Diane like most businesses negotiate a price for the
add'l services that she requires.
That's why it was so nice to have your own Class C network!
BY the time, we expanded out of a Class C, I was in "management"
and no long went to Cisco networking classes.
So I don;t need an intro to networking. I need an intro to Modern
Networking, with emphasis on Windows networking! I meant, NetBeui
and that stuff!! Really!! ;-)
