DHCP by Richard Lowe
At my day job, we were tasked with creating a Windows NT 4.0
network from blemish with alone basal training on the operating
system. We were experts at alive with OpenVMS and MacIntosh
systems, but none of us had anytime apparent Windows NT before. In those
days continued ago we were actual cocky, and actual aboveboard - how harder could
it be to set up a new TCP/IP network? Afterwards all, we had mastered
DECnet and Appletalk, could IP be any harder?
We anon abstruse the absurdity of our means - TCP/IP is far added complex
than we had originally believed. However, afterwards some head
scratching and a few buzz calls, we managed to get our network
up and running.
We didn t understand any better, so we artlessly harder coded the TCP/IP
address into anniversary workstation and server. In fact, we harder coded
everything, including the DNS and WINS server addresses, the
subnet and the aperture address.
For our purposes, this formed abundant for several years. We added
machines boring and planned aggregate far in advance, so it was
no big accord to just add a new apparatus to the network. A few
simple edits to the arrangement ascendancy console was all that was needed,
and back our arrangement was actual static, we didn t accept to visit
those ambience actual generally at all.
As our aggregation grew this arrangement started to get added and more
awkward. Originally we had a nice, isolated, self-contained
network, but now we bare to get on the internet, we were adding
not alone new workstations and servers at a bent rate, but we
had to accord with PDAs, handheld systems, standalone book servers
and hundreds of additional computers.
To create affairs even worse, area our arrangement was actual static,
now it was acceptable dynamic. computers would be added and removed
constantly - anyone would bung his handheld into an ethernet
jack, get their email, unplug and be gone.
The changeless TCP/IP arrangement that we had been using (a spreadsheet
with a account of machines and accompanying addresses) was artlessly no
longer working. Fortunately, there was an acknowledgment - DHCP.
The acronym DHCP stands for "Dynamic Host Agreement Protocol",
and it agency absolutely what it says. Already we apparent this new
tool we accomplished we had begin the band-aid to our problem - and
we kicked ourselves mentally for not account up on this wonderful
tool continued before.
To use DHCP is so aboveboard that the alone alibi for not
using it is abridgement of knowledge. You make a DHCP server -
depending aloft the admeasurement of your arrangement this can be added to an
existing server (the arrangement cartage is not usually actual high) or
you may charge to use a committed system. Some humans use the DHCP
server that comes with Windows NT or whatever operating system
they appear to be running. We begin the best band-aid was to
purchase a "DHCP appliance" - a baby computer advised to host
DHCP and alone DHCP.
Once you ve got your DHCP server installed, you use an interface
of some affectionate (often just any browser such as Internet Explorer)
to ascertain your arrangement parameters. These cover the ambit of
available TCP/IP addresses, the aperture address, the addresses
(primary and secondary) of your DNS or name servers, and any of
dozens of additional parameters.
Now comes the absolutely air-conditioned part. From this point forward, any
machine on your arrangement can, if told to do so, get all of the
TCP/IP advice from this DHCP server. This agency you no longer
need to access and/or change any of this data. It s all handled for
you. Windows 2000 Able systems even use DHCP by default,
which agency new workstations about plan out of the box.
To create this all simple for home users as well, some hardware
firewalls cover a DHCP server as allotment of the package. This
means if you get one of these firewalls (and it will acquaint you on
the box or instructions if it has a DHCP server built-in) you can
just bung computers in at home and not anguish actual abundant about
TCP/IP.
The basal band is there is no cause not to use DHCP for your
workstations, laptops and handheld accessories (it s not a acceptable idea
in accepted to use it for servers). You can even use it at home if
you get the able firewall.
