Computer Networks Practicals

Practical No	Details
1	IPv4 Addressing and Subnetting
a	Given an IP address and network mask, determine other information about the IP address such as: Network address Network broadcast address Total number of host bits Number of hosts
b	Given an IP address and network mask, determine other information about the IP address such as: The subnet address of this subnet The broadcast address of this subnet The range of host addresses for this subnet The maximum number of subnets for this subnet mask The number of hosts for each subnet The number of subnet bits The number of this subnet
2	Use of ping and tracert / traceroute, ipconfig / ifconfig, route and arp utilities.
3	Configure IP static routing.
4	Configure IP routing using RIP.
5	Configuring Simple OSPF.
6	Configuring DHCP server and client.
7	Create virtual PC based network using virtualization software and virtual NIC.
8	Configuring DNS Server and client.
9	Configuring OSPF with multiple areas.
10	Use of Wireshark to scan and check the packet information of following protocols HTTP ICMP TCP SMTP POP3
