Internet access vs. LANS Bruce Steinert, PhD - Urology Research 25 Jul 1995 08:17 EST

This sounds like an old "significant other's" tale to me. I can not
rule out the existance of restrictions for a computer that is supposed to
be dedicated to a specific project, but these should apply whether or not
the internet is involved.

From the technical aspect:

1. The IP address is how internet computers identify each other for ftp,
telnet, and email functions. The originating main computer (Domain Name Server
[DNS]) compares the names (e.g., xxxxxx@ALBNYDH2.BITNET) with the
corresponding IP address (Domain Name Resolution). The network then uses
the IP address to pass the message or request to the next computer in the
sequence et cetera, et cetera, et cetera until it arrives at the
destination DNS which recodes the name and delivers it to the desktop
PC. If no central computer is used to access the backbone, the desktop
computer or LAN server must take over the resolution function. Thus, each
computer, main frame or PC, must have a unique IP address whether
it resides on the backbone or a LAN. No IP, no access. Duplication or sharing
of IP addresses causes great distress among computer gurus.

Connections to the backbone are registered through the Internet Society
and conform to standards established by the Internet Architecture
Board. This is where the IP addresses are assigned. Lots of paperwork
involved, but technically feasible for a desktop PC.

....... so I've been told.

2. The only way to access the Web is by direct connection. The local PC
must be able to communicate one-on-one with the Web site's computer. This can
only be accomplished if both sites have IP addresses and there are no
routers or 'firewalls' in the pathway.

3. The Feds are trying to get funding proposal and report submissions
online. It seems woefully counter productive to set up an online system and
then forbid the primary users from accessing it just because Uncle Sam
bought the hardware. Come on, Congress is smarter that! Just look at the tax
code...sorry, bad example.

4. If the suspected CFR exists, I sure won't be the one to tell the Marines
to turn their computers off or else...

Hope that helps.
