The next Printer Server Setup Wizard window, Figure 4-13, shows TCP/IP setting for the print server. You can choose to use a dynamic IP address, which is the most common setting, for the print server. Then, select Obtain IP Address automatically. When select this option, there are two ways to get an IP address dynamically. The first one is to get an IP address from a DHCP server. If you have and use a home gateway/router, it usually comes with a DHCP server by default. The print server comes out of the factory as a DHCP client and can get an IP address automatically. The second way is to use a self-assigned IP address automatically. This is the same as a Microsoft Windows PC system. It is call Auto-IP.
Auto-IP
When NETGEAR PS101 Print Server is without an IP address due to as a DHCP client and there is no DHCP server to automatically get an IP address, it will self-assign a unique IP address. The address range is from 169.254.0.1 to 169.254.254.254 with the subnet mask 255.255.0.0 so that the print server can communicate and work with other IP devices using the same mechanism. To get the current IP address for the print server, make sure the printer power is ON, the print cable is connected to the PS101 print server, and the print server power is ON, press the diagnostic button for two seconds. The printer will print out the status of the print server, as well as the IP address.
How do I use this feature? Select Obtain IP Address automatically in Figure 4-13 Set up TCP/IP for Print Server to get an IP address. You do not use a DHCP server (usually if you don’t share a broadband – DSL, Cable, or satellite connection, you don’t have one). You are networking with Ethernet (including Fast- and Gigabit-Ethernet) network. Then you can use this feature. Your Microsoft Windows system uses this feature by itself. You can click on Start – Run, Enter ‘command’, and click OK. When the command prompt window is popped up, enter
Ipconfig
You may see the IP address for your system with 169.254.m.n, where m = 0-254 and n=1-254. The range is from 169.254.0.1 to 169.254.254.254 with the subnet mask 255.255.0.0 too. When you know the IP addresses for your system and the print server, you can test the connection from your PC to the print server. In the command prompt window, enter
Ping 169.254.x.y
Where 169.254.x.y is the IP address you get from the print out of the print server. (You should replace x and y with the IP address numbers in the print-out of the print server.)
You may set up a fixed IP address for the PS101 print server. Select Fixed IP Address. Please enter the IP address, Subnet mask, and Default gateway accordingly. You should get these values from your network administrator. If you don’t know what values you should use, you may use Suggest New Values button. This button is available only when you select Fixed IP Address. After click the Suggest New Value button, a set of values will be filled in the fields.

Appendix B Understanding IP Addresses
This appendix provides information about understanding IP addresses, which you must assign to the NETGEAR PS100 series Print Sever when operating in a TCP/IP environment.
IP Addresses and the Internet
Because TCP/IP networks are interconnected widely across the world, every machine on the Internet must have a unique address to make sure that transmitted data reaches the correct destination. Blocks of addresses are assigned to organizations by the Internet Assigned Numbers Authority (IANA). Individual users and small organizations may obtain their addresses either from the IANA or from an Internet service provider (ISP). The Internet Protocol (IP) uses a 32-bit address structure. The address is usually written in dot notation (also called dotted-decimal notation), in which each group of eight bits is written in decimal form, separated by decimal points. For example, the binary address:
11000011 00100010 00001100 00000111
is normally written as:
195.34.12.7
which is easier to remember and easier to enter into your computer. In addition, the 32 bits of the address are subdivided into two parts. The first part of the address identifies the network, and the second part identifies the host node or station on the network. The dividing point may vary depending on the address range and the application. There are five standard classes of IP addresses. These address classes have different ways of determining the network and host sections of the address, allowing for different numbers of hosts on a network. Each address type begins with a unique bit pattern, which is used by the TCP/IP software to identify the address class. After the address class has been determined, the software can correctly identify the host section of the address. The three main address classes are illustrated below, which shows the network and host sections of the address for each address type.
Three Main Address Classes
Class A addresses can have up to 16,777,214 hosts on a single network. They use an 8-bit network number and a 24-bit node number. Class A addresses are in this range:
1.x.x.x to 126.x.x.x.
Class B addresses can have up to 65,354 hosts on a network. Class B addresses use a 16-bit network number and a 16-bit node number. Class B addresses are in this range:
NetGear Print Server Manual
128.1.x.x to 191.254.x.x.
Class C addresses can have 254 hosts on a network. Class C addresses use 24 bits for the network address and 8 bits for the node. They are in this range:
192.0.1.x to 223.255.254.x.
Class D addresses are used for multicasts (messages sent to many hosts). Class D addresses are in this range:
224.0.0.0 to 239.255.255.255.
Class E addresses are for experimental use. This addressing structure allows IP to uniquely identify each physical network and each node on each physical network. For each unique value of the network portion of the address, the base address of the range (host address of all zeros) is known as the network address and is not usually assigned to a host. Also, the top address of the range (host address of all ones) is not assigned but is used as the broadcast address for sending a packet simultaneously to all hosts with the same network address.
Netmask
In each of the above address classes, the size of the two parts (network address and host address) is implied by the class. This partitioning scheme can also be expressed by a netmask associated with the IP address. A netmask is a 32-bit quantity that, when logically ANDed with an IP address, yields the network address. For instance, the netmasks for Class A, B, and C addresses are 255.0.0.0,
255.255.0.0, and 255.255.255.0, respectively. For example, the address 192.168.170.237 is a Class C IP address whose network portion is the upper 24 bits. When ANDed with the Class C netmask, as shown here, only the network portion of the address remains:
11000000 10101000 10101010 11101101 (192.168.170.237)
ANDed with:
11111111 11111111 11111111 00000000 (255.255.255.0)
Equals:
11000000 10101000 10101010 00000000 (192.168.170.0)
As a shorter alternative to dotted-decimal notation, the netmask may also be expressed in terms of the number of ones from the left. This number is appended to the IP address, following a backward slash ( / ), as "/n." In the example, the address could be written as 192.168.170.237/24, indicating that the netmask is 24 ones followed by 8 zeros.
NetGear Print Server Manual
Subnet Addressing
By looking at the addressing structures, you can see that even with a Class C address there are a large number of hosts per network. Such a structure is an inefficient use of addresses if each end of a routed link requires a different network number. It is unlikely that the smaller office LANs would have that many devices. You can resolve this problem by using a technique known as subnet addressing. Subnet addressing allows us to split one IP network address into smaller multiple physical networks known as subnetworks. Some of the node numbers are used as a subnet number instead. A Class B address gives us 16 bits of node numbers translating to 64,000 nodes. Most organizations do not use 64,000 nodes, so there are free bits that can be reassigned. Subnet addressing makes use of those bits that are free, as illustrated below.
Example of Subnetting a Class B Address
A Class B address can be effectively translated into multiple Class C addresses. For example, the IP address of 172.16.0.0 is assigned, but node addresses are limited to 255 maximum, allowing 8 extra bits to use as a subnet address. The IP address of 172.16.97.235 would be interpreted as IP network address 172.16, subnet number 97, and node number 235. In addition to extending the number of addresses available, subnet addressing provides other benefits. Subnet addressing allows a network manager to construct an address scheme for the network by using different subnets for other geographical locations in the network or for other departments in the organization. Although the preceding example uses the entire third octet for a subnet address, note that you are not restricted to octet boundaries in subnetting. To create more network numbers, you need only shift some bits from the host address to the network address. For instance, to partition a Class C network number (192.68.135.0) into two, you shift 1 bit from the host address to the network address. The new netmask (or subnet mask) is 255.255.255.128. The first subnet has network number 192.68.135.0 with hosts
192.68.135.1 to 129.68.135.126, and the second subnet has network number 192.68.135.128 with hosts
192.68.135.129 to 192.68.135.254.
The number 192.68.135.127 is not assigned because it is the broadcast address of the first subnet. And
192.68.135.128 is not assigned because it is the network address of the second subnet.
The table below lists the additional subnet mask bits in dotted-decimal notation. To use the table, write down the original class netmask and replace the 0 value octets with the dotted-decimal value of the additional subnet bits. For instance, to partition your Class C network 204.247.203.0 with subnet mask
255.255.255.0 into 16 subnets (4 bits), the new subnet mask becomes 255.255.255.240.

NETGEAR strongly advises that all hosts on a LAN segment use the same netmask for the following reasons:
So that hosts recognize local IP broadcast packets
When a device broadcasts to its segment neighbors, it uses a destination address of the local network address with all ones for the host address. In order for this scheme to work, all devices on the segment must agree on which bits comprise the host address.
So that a local router or bridge will know which addresses are local and which are remote
Private IP Addresses
If your networks are isolated from the Internet (for example, only between your two branch offices), you can assign any IP addresses to the hosts without problems. However, the IANA has reserved the following three blocks of IP addresses specifically for private networks:
10.0.0.0 - 10.255.255.255
172.16.0.0 - 172.31.255.255
192.168.0.0 - 192.168.255.255
NETGEAR recommends that you choose your private network number from this list. Regardless of your particular situation, do not create an arbitrary IP address; always follow the guidelines explained here. For more information about address assignment, refer to RFC 1918, Address Allocation for Private Internets, and RFC 2050, Guidelines for Management of IP Address Space .

Address Resolution Protocol
An IP address alone cannot be used to deliver data from one device to another on a LAN. In order for data to be sent from one device on the LAN to another, you must convert the IP address of the destination device to its media access control (MAC) address. Each device on an Ethernet network has a unique Ethernet MAC address, which is a 48-bit number assigned to each device by the manufacturer. The technique that associates the IP address with a MAC address is known as address resolution, and IP uses the Address Resolution Protocol (ARP) to do this. If a device needs to send data to another station on the network and it does not already have the destination MAC address recorded, ARP is used. An ARP request is broadcast onto the network, and all stations receive and read the request. The destination IP address for the chosen station is included as a part of the message so that only the station with this IP address responds to the ARP request and all other nodes discard it. The node with the right IP address responds with its own MAC address directly to the sender, providing the transmitting station with the destination MAC address needed for it to send the data. The IP address data and MAC address data for each node are held in an ARP table, so that the next time data needs to be sent, the address can be obtained from the address information in the table.
IP Configuration by DHCP
When an IP-based local area network is installed, each workstation must be configured with an IP address. If the workstations need to access the Internet, they should also be configured with a gateway address and one or more DNS server addresses. As an alternative to manual configuration, there is a method by which each device on the network can obtain this configuration information automatically. A device on the network may act as a Dynamic Host Configuration Protocol (DHCP) server. The DHCP server stores a list or pool of IP addresses, along with other information (such as gateway and DNS addresses) that it may assign to the other devices on the network. The NETGEAR Model RT328/RH348 router has the capacity to act as a DHCP server.
