D H C P (How to configure DHCP on your Network)
Rahul K Revlana. rkrevlana@gmail.com
DHCP
The DHCP server assigns a client an IP address taken from a predefined scope for a given amount of time. If an IP address is required for longer than the lease has been set for, the client must request an extension before the lease expires. If the client has not requested an extension on the lease time, the IP address will be considered free and can be assigned to another client. If the user wishes to change IP address then they can do so by typing "ipconfig /release", followed by "ipconfig /renew" in the command prompt. This will remove the current IP address and request a new one. Reservations can be defined on the DHCP server to allow certain clients to have their own IP address (this will be discussed a little later on). Addresses can be reserved for a MAC address or a host name so these clients will have a fixed IP address that is configured automatically. Most Internet Service Providers use DHCP to assign new IP addresses to client computers when a customer connects to the internet - this simplifies things at user level.
The above diagram diplays a simple structure consisting of a DHCP server and a number of client computers on a network.
The DHCP Server itself contains an IP Address Database which holds all the IP addresses available for distribution. If the client (a member of the network with a Windows 2000 Professional/XP operating system, for example) has "obtain an IP address automatically" enabled in TCP/IP settings, then it is able to receive an IP address from the DHCP server.
Setting up a DHCP Server
This will serve as a step-by-step guide on how to setup a DHCP server.
Installing the DHCP server is made quite easy in Windows 2003. By using the "Manage your server" wizard, you are able to enter the details you require and have the wizard set the basics for you. Open to "Manage your server" wizard, select the DHCP server option for the list of server roles and press Next.
You will be asked to enter the name and description of your scope.
Scope: A scope is a collection of IP addresses for computers on a subnet that use DHCP.
The next window will ask you to define the range of addresses that the scope will distribute across the network and the subnet mask for the IP address. Enter the appropriate details and click next.
You are shown a window in which you must add any exclusions to the range of IP addresses you specified in the previous window. If for example, the IP address 10.0.0.150 is that of the company router then you won't want the DHCP server to be able to distribute that address as well. In this example I have excluded a range of IP addresses, 10.0.0.100 to 10.0.0.110, and a single address, 10.0.0.150. In this case, eleven IP's will be reserved and not distributed amongst the network clients.
It is now time to set the lease duration for how long a client can use an IP address assigned to it from this scope. It is recommended to add longer leases for a fixed network (in the office for example) and shorter leases for remote connections or laptop computers. In this example I have set a lease duration of twelve hours since the network clients would be a fixed desktop computer in a local office and the usual working time is eight hours.
You are given a choice of whether or not you wish to configure the DHCP options for the scope now or later. If you choose Yes then the upcoming screenshots will be of use to you. Choosing No will allow you to configure these options at a later stage.
The router, or gateway, IP address may be entered in next. The client computers will then know which router to use.
In the following window, the DNS and domain name settings can be entered. The DNS server IP address will be distributed by the DHCP server and given to the client.
If you have WINS setup then here is where to enter the IP Address of the WINS server. You can just input the server name into the appropriate box and press "Resolve" to allow it to find the IP address itself.
The last step is to activate the scope - just press next when you see the window below. The DHCP server will not work unless you do this.
The DHCP server has now been installed with the basic settings in place. The next stage is to configure it to the needs of your network structure.
Configuring a DHCP server
Hereunder is a simple explanation of how to configure a DHCP server.
The address pool displays a list of IP ranges assigned for distribution and IP address exclusions. You are able to add an exclusion by right clicking the address pool text on the left hand side of the mmc window and selecting "new exclusion range". This will bring up a window (as seen below) which will allow you to enter an address range to be added. Entering only the start IP will add a single IP address.
DHCP servers permit you to reserve an IP address for a client. This means that the specific network client will have the same IP for as long as you wanted it to. To do this you will have to know the physical address (MAC) of each network card. Enter the reservation name, desired IP address, MAC address and description - choose whether you want to support DHCP or BOOTP and press add. The new reservation will be added to the list. As an example, I have reserved an IP address (10.0.0.115) for a client computer called Andrew.
If you right click scope options and press "configure options" you will be taken to a window in which you can configure more servers and their parameters. These settings will be distributed by the DHCP server along with the IP address. Server options act as a default for all the scopes in the DHCP server. However, scope options take preference over server options.
In my opinion, the DHCP server in Windows 2003 is excellent! It has been improved from the Windows 2000 version and is classified as essential for large networks. Imagine having to configure each and every client manually - it would take up a lot of time and require far more troubleshooting if a problem was to arise. Before touching any settings related to DHCP, it is best to make a plan of your network and think about the range of IPs to use for the computers.

INTERVIEW QUESTIONS
Q: What is an IP address?
An Internet Protocol (IP) address is a numerical identification and logical address that is assigned to devices participating in a computer network utilizing the Internet Protocol for communication between its nodes
Q: What is a subnet mask?
Q: What is ARP?
ARP is the Address Resolution Protocol. The ARP protocol maps addresses between the Data Link Layer and the Network Layer of the OSI Model.
Q: What is ARP Cache Poisoning?
ARP poisoning or ARP Poison Routing (APR), is a technique used to attack an Ethernet wired or wireless network. ARP Spoofing may allow an attacker to sniff data frames on a local area network (LAN), modify the traffic, or stop the traffic altogether (known as a denial of service attack). The attack can only be used on networks that actually make use of ARP and not another method of address resolution
Q: What is the ANDing process?
In order to determine whether a destination host is local or remote, a computer will perform a simple mathematical computation referred to as an AND operation. While the sending host does this operation internally, understanding what takes place is the key to understanding how an IP-based system knows whether to send packets directly to a host or to a router.
An AND operation is very simple – two binary digits are compared, and the based on their combination, a resultant value is formed. It is neither adding nor subtracting, so do not consider it as such. In the most simple terms, there are only three possibilities when ANDing two binary digits. The list below outlines these operations and their results.
Q: What is a default gateway? What happens if I don't have one?
In computer networking, a default gateway is the device that passes traffic from the local subnet to devices on other subnets. The default gateway often connects a local network to the Internet, although internal gateways for local networks also exist.
Q: Can a workstation computer be configured to browse the Internet and yet NOT have a default gateway?
If we are using public ip address, we can browse the internet. If it is having an intranet address a gateway is needed as a router or firewall to communicate with internet.
Q: What is a subnet?
Q: What is APIPA?
A feature of Microsoft Windows, APIPA is a DHCP failover mechanism. With APIPA, DHCP clients can obtain IP addresses when DHCP servers are nonfunctional. APIPA exists in all popular versions of Windows except Windows NT.
When a DHCP server fails, APIPA allocates addresses in the private range 169.254.0.1 to 169.254.255.254. Clients verify their address is unique on the LAN using ARP. When the DHCP server is again able to service requests, clients update their addresses automatically.
Q: What is an RFC? Name a few if possible (not necessarily the numbers, just the ideas behind them)
A Request For Comments (RFC) document defines a protocol or policy used on the Internet. An RFC can be submitted by anyone. Eventually, if it gains enough interest, it may evolve into an Internet Standard ( see FAQ XXX). Each RFC is designated by an RFC number. Once published, an RFC never changes. Modifications to an original RFC are assigned a new RFC number
An Internet Document can be submitted to the IETF by anyone, but the IETF decides if the document becomes an RFC. Eventually, if it gains enough interest, it may evolve into an Internet standard.
Each RFC is designated by an RFC number. Once published, an RFC never changes. Modifications to an original RFC are assigned a new RFC number.

An Internet Protocol (IP) address is a numerical identification and logical address that is assigned to devices participating in a computer network utilizing the Internet Protocol for communication between its nodes
Q: What is a subnet mask?
Q: What is ARP?
ARP is the Address Resolution Protocol. The ARP protocol maps addresses between the Data Link Layer and the Network Layer of the OSI Model.
Q: What is ARP Cache Poisoning?
ARP poisoning or ARP Poison Routing (APR), is a technique used to attack an Ethernet wired or wireless network. ARP Spoofing may allow an attacker to sniff data frames on a local area network (LAN), modify the traffic, or stop the traffic altogether (known as a denial of service attack). The attack can only be used on networks that actually make use of ARP and not another method of address resolution
Q: What is the ANDing process?
In order to determine whether a destination host is local or remote, a computer will perform a simple mathematical computation referred to as an AND operation. While the sending host does this operation internally, understanding what takes place is the key to understanding how an IP-based system knows whether to send packets directly to a host or to a router.
An AND operation is very simple – two binary digits are compared, and the based on their combination, a resultant value is formed. It is neither adding nor subtracting, so do not consider it as such. In the most simple terms, there are only three possibilities when ANDing two binary digits. The list below outlines these operations and their results.
Q: What is a default gateway? What happens if I don't have one?
In computer networking, a default gateway is the device that passes traffic from the local subnet to devices on other subnets. The default gateway often connects a local network to the Internet, although internal gateways for local networks also exist.
Q: Can a workstation computer be configured to browse the Internet and yet NOT have a default gateway?
If we are using public ip address, we can browse the internet. If it is having an intranet address a gateway is needed as a router or firewall to communicate with internet.
Q: What is a subnet?
Q: What is APIPA?
A feature of Microsoft Windows, APIPA is a DHCP failover mechanism. With APIPA, DHCP clients can obtain IP addresses when DHCP servers are nonfunctional. APIPA exists in all popular versions of Windows except Windows NT.
When a DHCP server fails, APIPA allocates addresses in the private range 169.254.0.1 to 169.254.255.254. Clients verify their address is unique on the LAN using ARP. When the DHCP server is again able to service requests, clients update their addresses automatically.
Q: What is an RFC? Name a few if possible (not necessarily the numbers, just the ideas behind them)
A Request For Comments (RFC) document defines a protocol or policy used on the Internet. An RFC can be submitted by anyone. Eventually, if it gains enough interest, it may evolve into an Internet Standard ( see FAQ XXX). Each RFC is designated by an RFC number. Once published, an RFC never changes. Modifications to an original RFC are assigned a new RFC number
