Question

Compare classfull IP addressing with classless IP addressing. Why was classless IP addressing designed?

Answer 1

Classfull Addressing
Classfull addressing incorporates a three-part read. In classful routing, the address is split into 3 elements that are: Network, Subnet, and Host. The IPv4 protocol uses a thirty-two-bit address area. In classful address, this area is split into 5 classes: A, B, C, D, and E. Classes A, B, C contains netid and hostid. Classful Routing doesn't import subnet mask. And during this conjoint subnet mask is provided once the route update. In classful routing, the subnet mask is that the same throughout doesn't vary for all devices
Classless Addressing
Classless addressing uses a two-part read of IP addresses.in democratic routing, the address is split into 2 elements that are: Subnet and Host. In democratic addressing, variable-length blocks are assigned that belongs to no category.it imports subnet mask and during this, triggered updates ar used. and the subnet mask isn't an equivalent throughout, it's going to vary for all devices.
CLASS FULL ADDRESSING
⦁ in classful addressing needs a lot of bandwidth.
⦁ In classful addressing, hi messages don't seem to be used.
⦁ in classful addressing doesn't import subnet mask.
⦁ In classful addressing, the address is split into 3 elements that are: Network, Subnet, and Host.
⦁ In classful addressing, regular or periodic updates ar used.
⦁ In classful addressing, CIDR(Classless Inter-Domain Routing) isn't supported.
⦁ In classful addressing, subnets don't seem to be displayed in alternative major subnets.
CLASSLESS ADDRESSING
⦁ it needs less information to measure
⦁ hi, messages are used.
⦁ it imports a subnet mask.
⦁ the address is split into 2 elements that are: Subnet and Host.
⦁ triggered updates ar used.
⦁ CIDR(Classless Inter-Domain Routing) is supported.
⦁ subnets are displayed in alternative major subnets
Classless IP addressing designed as a result of classful routing space allocation is obtainable in classless addressing. Memory is allotted in terms of bits and bytes instead of large chunks of contiguous memory. It eliminates any category imbalances. Routing entries are rather more economical.it enables specific data packets to be sent to particular computers.
