CLSM (Constant Length sub net Mask). Whenever we are Using Same Sub net Mask in entire Organization, that architecture Is Called CLSM in the Network.
VLSM (Variable Length Sub net mask) in the Network. Whenever we are Using different-different sub net Mask in entire Organization, that architecture Is Called VLSM.
Classless protocols send a subnet mask with each route advertisement
Rip V1 is Classful routing protocol Rip V2 is Classless routing Protocol
If you combine multiple classful networks it is supernetting, when you make them smaller you are subnetting . CIDR is a condition where you no longer consider the classful boundries. You no longer need to think of the words subnetting or supernetting really because everything is a simple division between network and host.
The difference between classful IP addressing and classless IP addressing is in selecting the number of bits used for the network ID portion of an IP address. In classful IP addressing, the network ID portion can take only the predefined number of bits 8, 16, or 24. In classless addressing, any number of bits can be assigned to the network ID.
Classful vs. Classless RIPv1 is a classful protocol, meaning that the subnet mask is not included in the routing updates. With RIP, only the default subnet mask is used to identify networks. RIP v2 is a classless protocol, meaning that the subnet mask IS included in the routing tables.. RIPv2 supports variable subnet masks (VLSM).
A classless routing protocol can route between subnets
More commonly referred to as classless routing behaviour in reference to protocols. examples are ripv2, eigrp, ospf, isis etc. classless routing protocols submit subnet information in the data they send to other routers. therefore, variable subnet masks can be applied other than the default classful subnet mask. i.e, if the first two bits in the first octet are 0 then it is a class A address, and the first octet only, /8 or 255.0.0.0, is the network portion. hence why the private routing address 10.0.0.0 extends all the way to 10.255.255.255. with classless routing behaviour this can be any subnet mask.
RIPv1 (Routing Information Protocol version 1) has several limitations, one of the most significant being its lack of support for subnetting due to its reliance on classful addressing. This leads to inefficiencies, as it cannot provide routing updates for subnets or differentiate between networks of different sizes. Additionally, RIPv1 does not support authentication, making it vulnerable to routing table attacks. Its maximum hop count of 15 also limits its scalability in larger networks.
Communism: a classless stateless society based on common ownership and production for use. Fascism: an authoritarian variety of capitalism, with wages system, production for sale and no democratic rights.

SUBNET: subnet is a group of networks having same network id. subnet increase the number of hosts with same network address, as result it reduces the wastage of addresses. In subnetting bits of hostId will be captured by networdId. SUPERNET: supernet makes all the hosts with in a range of network address belong to a same group. This reduces the entries in the network address table. Supernetting combines the octets of the address.
False. The Internet Assigned Numbers Authority (IANA) did not implement classful IPv6 addresses, as IPv6 does not use classful addressing. Instead, IPv6 employs a hierarchical addressing structure based on allocation sizes and prefixes, allowing for efficient routing without the need for classes like in IPv4.
