Computer Networks Practicals

Practical NoDetails
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
