Hello people, hope you are all well.

I was wondering if anybody could help me with an assignment working on. Basically I have a network that consists of computers routers, dhcp server, web server, file server and a print server. I am installing Windows 2003 server for this network and I have to take into consideration of assigning automatic, static, public and private ip addresses.

My question is where would I use a static, automatic, public and private ip addresses?

From what I have researched so far, I think that public IP addresses would be used for the print, file and web servers. Private IP addresses would be used for an intranet. The DHCP server would need an automatic IP address and the computers connected to the network would be static ip addresses.

Can anyone confirm that I am on the right lines or has a different view from me. Thank you very much in advance.

Public IPs are used to publish services through the internet.
So if you plan to let people access your server from the internet, your server needs a public ip or, if your server is behind a router firewall, you need a port forwarding from the router to your server for the needed port.

Private IPs are used to connet to any internal (private network) server or workstation.
So the server must also have a private IP for the internal connections.

Static IPs are use for servers or IP printers.
So the IP will never change and the services can be accessed alway by using the same IP.
Servers do always have a static IP.

Automatic or dynamic IPs are assigned to the workstations inside your local network by the DHCP server that you plan to run at the W2K3 server.

I hope that helps.

Thank you for your indepth reply paulsep, I have managed to get a better idea on what sort of ip addresses i should be assinging. If I am correct, I dont think I would be needing a public or private IP address at all. This is because my servers would need to be static and everything else are workstations so they would be getting automatic ip addresses from the dhcp server.

Here is the actual scenario I am working on:

Your company has decided to implment DHCP as a solution to the automation of IP addresses. Your network consists of four network segments connected by three routers. The current network consists of the following:

- A single LAN consisting of four subnets with clients attatched to all of them.

- Subnet A consists of 100 computers, web server and a rpxy server

- subnet b consists of 80 computers, a print server and a file server

- subnet c consists of 50 computers, file and print server and a web server

- subnet d consists of 20 computers and a web server

- access to web-based intranet resoyurces and access to the internet from all locations

- screening from the internet through a proxy server and firewall

- dhcp/bootp forwarding on all routers

So this is a homework assignment, and you want us to provide the resolution and do the assignment for you?

Life's more painless for the brainless.

Just right !!!
But keep in mind, the local DHCP server is assigning private IP automatically.
So the workstations will get a private IP dynamically.
Mostly the lease time is 3 days, so if one client computer is of for about 3 days, the DHCP server leases the IP of that client computer and uses it for the next client that needs a new ip address.

You're right, it is homework.
Basic knowledge for playing with networks.

:-)

no not really, the assignment involves me physically istalling windows 2003 server, installing and authorising a dhcp server, creating and configuring scopes and scope options and then installing dhcp relay agents. But before all this I have to subnet the network in order to to choose the right class to provide ip addresses for al the nodes.

thank you very much for all your help paulsep. god bless.

"I dont think I would be needing a public or private IP address at all."

this understanding is incorrect.

Imagine the power of knowing how to internet search

you need private and public
private adresses are hidden from the internet. so anything form the internet cant connect to a private adress.
public aint.
so private would be servers printers and computers dont want any one outside getting to them.
if you have a internet site thats hosted on a server then thats public.

just rember the unwritten golden rule
asign the first ip adress upwards for routers and servers and printers(not sure about printers) all static ip adresses

and use the last ip adress downwards for the hosts eg computers(dynamic)

oh and this just from looking at it needs a vlsm could put in room for growth if the adress allows it. and rember the that you need a network adress and broadcast adress. so add two to all the networks. including the networks that are between routers on the serial conections

also looking at the problem i got this nagging feeling that you might have to watch what part of the topology that you put the servers and printers so that the load is spread out on the network.

sorry im lost what is this work for? because it sounds like your really shaky on the basic concepts.

all text needs typos. There there for the reader to find,to distract them from the total lack of content.
google it! wasnt the answer to the question i asked so dont be dense and give me that repl

And I wouldn't recommend "playing" with networks if you actually want them to function properly. They're not toys.
