The /20 subnet mask is the subnet mask with dotted decimal notation of 255.255.240.0 and the wildcard mask of 0.0.15.255. /20 subnet mask divides larger networks like class A and class B networks into smaller networks (subnetworks). Each of these subnetworks has a range of 4096 IP addresses. The first IP address in this range is […]

The /21 subnet mask is a subnet mask with dotted decimal notation of 255.255.248.0 and a wildcard mask of 0.0.7.255. 21 subnet masks divide larger networks, like class A networks and class B networks, into smaller networks (subnetworks). Each of the subnetworks has a range of 2048 IP addresses. The first IP address in this

/22 A subnet mask is a subnet mask with a dotted decimal notation of 255.255.252.0 and a wildcard mask of 0.0.3.255. /22 subnet masks divide larger networks, like class A and class B networks, into smaller networks (subnetworks). Each of the subnetworks has a range of 1024 IP addresses. The first IP address in this
/23 subnet mask is a subnet mask with 255.255.254.0 as the dotted decimal notation and 0.0.1.255 as the wildcard mask. /23 subnet mask divide larger network like class B network and Class A networks into a smaller networks(subnetworks). Each of the subnetworks has 512 range of IP addresses. The first IP address in this range
The /24 subnet mask is the default subnet mask for a class C network, which includes all networks from 192.0.0.0 to 223.255.255.0. /24 subnet mask has a dotted decimal of 255.255.255.0, and this is obtained by converting its binary representation, 11111111.11111111.11111111.00000000, into a dotted decimal. A /24 subnet mask gives 256 ranges of IP addresses.

The /25 subnet mask divides a large network into multiple smaller subnetworks. Each of the subnetworks comprises 128 ranges of IP addresses. The first IP address in this range is reserved as the network address, while the last IP address in this range is reserved as the broadcast IP address. Hence, there are 126 usable
In classless interdomain routing (CIDR), the /32 subnet mask is one of the prefix lengths that is most confusing. Unlike the /31 subnet mask and other subnet masks we covered earlier, the /32 subnet mask does not divide a network into subnetworks; it rather defines the host route. Once you assign an IP address to
The /31 subnet mask, just like the /30 subnet mask, is a prefix length used in point-to-point connections between two network devices. A /31 subnet mask divides a large network into subnetworks with just 2 ranges of IP addresses. Unlike other subnet masks, /31 does not have a network address or a broadcast IP address.
A /30 subnet mask is a prefix length commonly used in a point-to-point connection between two network devices. A /30 network divides a large network into a very smaller network containing just 4 ranges of IP addresses. The first IP address in this range is the network ID, and the last IP address in this
A /29 subnet mask is a prefix length that divides a larger network into multiple smaller subnetworks. Each of the subnetworks will have a maximum of 8 IP address ranges. The first IP address in this range is used as the network address, while the last IP address in this range is used as the
