How do subnet masks indentify that a network has been subnetted?

If (for example) the first 20 bits of the subnet masks are "1", then any IP address that shares the same 20 bits with the IP address of my computer is in the same subnet.
Note that a subnet only indicates the size of the current subnet, the subnet in which your computer (for example) is located. Other subnets of a network may have different sizes; this can't be ascertained just by looking at you IP address and subnet. Nor is it relevant for your computer: The computer only has to know that anything outside the subnet has to be sent first to the default gateway - the server or router that connects your subnet to the remainder of the net.

∙ 14y agoThink of a subnet as a smaller network within a larger network. Therefore, the subnet id identifies a subnet as being another part of the larger network. You need to route packets between subnets because a subnet is treated as a separate network.

Why do you think the IP addresses are different but the subnet masks and default gateways are the same?
Because you have a DHCP server in the network.
What is a static length subnet mask?
That probably refers to a situation where a larger network was divided into smaller subnets, but all subnets have the same size - as opposed to VLSM (variable length subnet masks), where subnets can have different sizes.That probably refers to a situation where a larger network was divided into smaller subnets, but all subnets have the same size - as opposed to VLSM (variable length subnet masks), where subnets can have different sizes.That probably refers to a situation where a larger network was divided into smaller subnets, but all subnets have the same size - as opposed to VLSM (variable length subnet masks), where subnets can have different sizes.That probably refers to a situation where a larger network was divided into smaller subnets, but all subnets have the same size - as opposed to VLSM (variable length subnet masks), where subnets can have different sizes.

How tocalculate subnet mask address?
Calculating a subnet mask depends on whether you are using the default, classful mask or a true subnet mask to divide a network into smaller pieces.The defaults are on octet boundaries (every 8 bits):255.0.0.0 class A network255.255.0.0 class B network255.255.255.0 class C networkAny other type of subnet mask with 4 octets (iPV4) can use combinations of those with any octet value from 0 - 255. No number may be larger than 255.Calculating other subnet masks would be based on how many subnets you want in the network. You could have values such as:255.192.0.0255.255.248.0.0255.255.255.252The first octet must at least be 255. The other octets may change, based on whether it is a classful default network or it is being subnetted.

IP subnet masks allows for up to 30 hosts per subnet?
255.255.255.224 will select a network of 32 IP addresses, with the lowest reserved as the network identifier, and the highest as the broadcast address, leaving 30 usable host IP addresses.
