The aim of this activity is to understand how
network addresses are set, on both networking devices
and hosts. Network addresses are defined with 0's
in the host part, thus for a subnet mask of 255.255.255.0,
and a Class B address of 146.176.y.z, then the following
will be subnet network addresses: 22.214.171.124,
126.96.36.199, and so on. Routers are typically used
to split the network up into subnetworks (subnets).
Each port of the router must be assigned an address
from the range of addresses from the subnet address
pool. Typically this address is either the first
or the last in the address pool, such as 188.8.131.52
for the 184.108.40.206 network.
1: Network addresses
Time to complete: Approx 5 minutes
On the network nodes are address using both their
physical address and their network address. When
the node is on another interconnected network it
is only necessary to use its network address, as
the physical address only has local significance.
The most popular network addresses are:
IP address: 192.168.0.10
IPX address: 2B10.0000.00CC.0125
The NetBIOS name is used in Microsoft Windows networks,
and has significance within a Windows domain. When
a node is created in a Windows environment it is
given a NetBIOS name (such as freds_pc in the example
IPX uses a 12-byte station address (whereas IP
uses a 4-byte address), which is made up of:
Network part. This uses the 32
bits of the network address. This is assigned by
the network administrator. In the example above
this is 2B10.
Node part. This typically uses
the 48-bit MAC address of the node, and is automatically
assigned. In the example above this is 0000.00CC.0125.
2: IP address allocation
Time to complete: Approx 10 minutes
In this activity you should assign the addresses
by dragging the red boxes onto the black boxes.
In a network a network address contains 0's in the
host part of the address, whereas nodes and router
ports must have a unique IP address. In the activity
there are a number of address which require to be
allocated onto each of the subnetworks.
3: Setting IP addresses on hosts
Set the IP address to 192.168.0.3
Set the subnet mask to 255.255.255.0
The gateway address relates to port of the
router which it connects to, thus set the
gateway address to 192.168.0.1
Set the DNS server to 220.127.116.11
There is no on-line test this week, as there is
a formal test.
