So, if we use a given address with a higher Subnet Mask value like given in the second example, we will have more networks. In other words, we can divide the network into smaller pieces. So, we will not waste the IP Addresses. Smaller networks that has few hosts do not need more addresses. With Subnetting, using a small network with few host addresses is a way of best practice of a network engineer.
Incorrect Subnet Mask: If a network uses a subnet mask other than the default mask for its address class, and a client is still configured with the default subnet mask for the address class, communication will fail to some nearby networks but not to distant ones. As an example, if you create four subnets (such as in the subnetting example) but use the incorrect subnet mask of 255.255.255.0 in your TCP/IP configuration, hosts won't be able to determine that some computers are on different subnets than their own. In this situation, packets destined for hosts on different physical networks that are part of the same Class C address won't be sent to a default gateway for delivery. A common symptom of this issue is when a computer can communicate with hosts that are on its local network and can talk to all remote networks except those networks that are nearby and have the same class A, B, or C address. To fix this problem, just enter the correct subnet mask in the TCP/IP configuration for that host.
VLSM (Variable Length Subnet Mask) is a technique that allows network administrators to divide an IP address space into subnets of different sizes, rather than dividing it into subnets of the same size. This allows for more efficient use of IP addresses, as smaller subnets can be used for smaller networks, and larger subnets can be used for larger networks.\nFor example, if a network administrator is given a Class C IP address space of 192.168.1.0\/24, they can use VLSM to divide it into two subnets: one with a \/25 mask for a smaller network, and one with a \/26 mask for a larger network. The smaller network would have 128 host addresses, and the larger network would have 64 host addresses.\nThis allows the administrator to assign IP addresses more efficiently, as they can use the larger subnet for a network that needs more IP addresses and the smaller subnet for a network that needs fewer IP addresses.\n\n\n","author":"@type":"Person","name":"Amakiri Welekwe","description":"Amakiri is a UK-trained technology consultant and cybersecurity evangelist, working at the intersection of security, technology, and people.
