Classful Internet address
IP address is 32 bit( dotted decimal notation for IP address)
IP address is a hierarchical address IP address is location based .
The designers are free to choose packet format and sizes addresses delivery techniques and so on..
Nothing is dictated by the hardware.
For addresses the designers of TCP IP chose scheme analogous to Physical network addressing in which each Host on the internet is assigned 32 bit integer address called its internet address or IP address
Integer are chosed carefully to make routing efficient.
IP address encodes the identification of the network to which a host attaches as well as identification of a unique host. EA is a pair ,net IDand host ID .net ID identifies the network and host ID identifies a host on that network each address is a pair (net ID ,host ID)
Net ID identifies a network
host ID identifies a host on that network
The partition into prefix and suffix is not uniform throughout the entire internet because the designer did not specify a single boundary
In the original addressing scheme which is known as class full each IP address had one of the first three form.
In the classful addressing scheme each address is said to be self identify because the boundary between prefix and suffix can be computed from the address alone without reference to external information
Subnet and supernet (classless addresses )extensions
A unique prefix for each physical network would exhaust the address space quickly consequently an Addressing extension was developed to conserve network prefix known as subnet addressing scheme allows multiple physical networks to share a prefix.
A second extension was devised that ignored the classful heirarchy and allowed the division b/w perfix and suffix to occur at arbitary point called classles addressing or supernetting .
The scheme allows more complete utilization of the address space
