Subnets allow to isolate traffic within a subnet. It is beneficial not only from security perspective but also from performance.
5 bits are necessary to create up to 30 subnets.
No
Depending on class of network you are planning to use. For class C you can create much more then that (and for the most case for others too).

To create more subnets, you can use subnetting, which involves dividing a larger network into smaller, manageable segments. This is achieved by borrowing bits from the host portion of an IP address to create additional network bits, effectively increasing the number of available subnets. For example, if you start with a /24 subnet and borrow 2 bits, you can create 4 additional subnets with a /26 prefix. Ensure that the subnet mask and addressing scheme align with your network design and requirements.

To divide the network 192.168.1.0/24 into 6 subnets, we need to determine the subnet mask that accommodates at least 6 subnets. Using a /26 subnet mask (which allows for 4 subnets), we can go to /25 (which allows for 2 subnets) or /27 (which allows for 8 subnets). With a /27 subnet mask (255.255.255.224), we can create 8 subnets, each with 30 usable IP addresses. The resulting subnets would be: 192.168.1.0/27, 192.168.1.32/27, 192.168.1.64/27, 192.168.1.96/27, 192.168.1.128/27, and 192.168.1.160/27.
To create 8 subnets for the IP address 192.168.1.0, you need to use subnetting. Since 8 subnets require 3 additional bits (as 2^3 = 8), you can take 3 bits from the host part of the default subnet mask (255.255.255.0 or /24). This will change the subnet mask to 255.255.255.224 (/27), allowing for 8 subnets, each with 30 usable host addresses (2^5 - 2 = 30). The resulting subnets will range from 192.168.1.0 to 192.168.1.224.
The IPv6 prefix 2001:db8:3000:52::/64 indicates that the first 64 bits are used for the network portion. With a /64 subnet, the administrator can create 2^(128-64) = 2^64 subnets, which equals 18,446,744,073,709,551,616 possible subnets. Thus, the administrator has an enormous number of subnets available to allocate.

Although VLANs and subnets are quite different concepts, when using VLANs, there should be a one-to-one correspondence between the two. That is, every VLAN should be in a different subnet.Although VLANs and subnets are quite different concepts, when using VLANs, there should be a one-to-one correspondence between the two.
