1. With a schematic explain the TCP/IP architecture.

2. Explain IP packet header.

3. Explain the need for classification of IP Addressin and !u"net addressin#

$. Explain %ith an example the role of !u"net mask.

&. A net%ork on the internet has a su"net mask 2&&.2&&.2$'.'. What is the maximum no. of hosts it

can handle#

(. A host in an orani)ation has an IP address 1&'.32.($.3$ and a su"net mask 2&&.2&&.2$'.'. What

is the address of this su"net# What is the rane of IP addresses that a host can ha*e on this su"net#

+. Explain ho% routin is done in IP#
