Card 1
HintThink about the number of bits used for network vs. host addresses.Memory TipRemember: /28 means '28 bits for the network'
Card 2
HintIt's like a dividing line between the network address and the specific device on that network.Memory TipSubnet mask = Network vs. Host
Card 3
HintThink about how an address can be split to identify both the network and the specific device on it.Memory TipNetwork & Host = Two sides of the IP address coin!
Card 4
HintStart with the total addresses possible for 6 bits, then subtract the unusable ones.Memory Tip6 bits = 64, then subtract 2 for network and broadcast
Card 5
HintThink about how many unique addresses can be generated with 5 bits, then subtract the unusable ones.Memory Tip5 bits = 32 total addresses, subtract 2 for network and broadcast
Card 6
HintThe subnet mask tells you where the network portion of the IP address ends.Memory TipSubnet Mask = Dividing Line
Card 7
HintThink about how many unique addresses can be generated with 4 bits and what addresses are not used.Memory Tip4 bits = 16 total addresses, subtract 2 for network and broadcast
Card 8
HintConsider which address range it falls within and whether it is a specific device or a reserved address.Memory TipHost addresses are between network and broadcast addresses
Card 9
HintThe prefix length reflects the number of '1' bits in the subnet mask, representing the network portion.Memory TipThink of it like a code: the more '1' bits, the shorter the host portion and the more specific the network address
Card 10
HintThe number of host bits determines the range of usable addresses. Subtract 2 to account for network and broadcast addresses.Memory TipRemember, 2^n gives the total IPs, then remove 2 for network and broadcast
Card 11
Hint5 host bits mean 27 network bits. Convert the binary representation to its decimal equivalent for the subnet mask.Memory TipSubtract host bits from 32 to find network bits
Card 12
HintBorrowed bits for subnetting determine the number of subnets possible.Memory Tip2 raised to the power of borrowed bits equals the number of subnets
Card 13
HintThe slash notation indicates network bits, directly translating to the subnet mask.Memory TipThink of it as '20 network bits = 224 as the last octet'
Card 14
HintIt allows flexibility in subnet sizes to meet different network needs.Memory TipVariable size, efficient addressing
Card 15
HintThe result of the AND operation determines the network address.Memory TipFilter out the 'host part' of the IP address for network identification
Card 16
HintCalculate total addresses using 2^n, then subtract 2 for network and broadcast.Memory TipHost bits determine total IPs, reduce by 2 for usable IPs
