utilize multiple subnet masks in the same IP address space
variable length subnet masks
subnet masks
Because you have a DHCP server in the network.
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.
This IP address can work with a variety of different subnet masks.This IP address can work with a variety of different subnet masks.This IP address can work with a variety of different subnet masks.This IP address can work with a variety of different subnet masks.
The DHCP protocol is used for this purpose.
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.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.

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.
The site below has a fairly good explaination of the uses of subnet masks.
No, all subnets must use the same subnet mask
Subnet masks that use either all ones or all zeroes in an octet are called classful subnet masks. 255.255.255.0 (11111111.11111111.11111111.00000000), 255.255.0.0 (11111111.11111111.00000000.00000000), 255.0.0.0 (11111111.00000000.00000000.00000000)
