The document discusses TCP/IP addressing and related concepts. It introduces TCP/IP and its layered architecture, with a focus on addressing at the network, transport, and physical layers. It describes IP address classes and subnetting as ways to allocate addresses and networks, and how CIDR and variable length subnet masking improved on these methods.

MASKING It helps in knowing which portion of given IP address identifies network and which identifies host. Default mask for : A -> 255.0.0.0 B -> 255.255.0.0 C -> 255.255.255.0
