A short description of the problem:
Usually, in the internet one accesses only those servers
which are permanently connected to the internet
which have a unique name.
If you connect to the internet via an internet access provider, then
usually you have only client status, since due to your
dynamic IP the permanently valid name is missing.
For sales representatives it would certainly be desirable to access
the company network from anywhere. Thus, customers could be presented with
information from the company intranet ...
It would be especially practical, though, if one could quickly get important
information from the company fileserver at home, late at night, in order to
be well prepared for the next day's business trip ...
... and that from anywhere in the world.
For companies with enough petty cash, certainly not a problem - VPN and
e.g. SDSL with a static IP would be the solution.
The problem is thus finding an affordable solution for
any company size.
Since the advent of online games, i.e. several
players playing a game while connected via the internet, the phones are
The telephone calls are short - strange combinations of numbers are quickly
The basis for the solution is just this combination of numbers which
online gamers exchange! It is their current IP(*) - their
"unique identification" on the internet
... but in practice this is difficult.
How does one determine the IP of the
current internet connection?
... but in practice this is troublesome.
A new IP is assigned for each new
which must be exchanged again.
Our solution, in contrast, is simple!
(*)IP: An IP is a
combination of numbers of the form 220.127.116.11. Every computer connected
to the internet is assigned such a combination of numbers. This combination
of numbers is comparable to a telephone number - unique worldwide.
