What subnet mask must you use (show the subnet mask in decimal and binary)?
Decimal Subnet mask: __________ . __________ . __________ . __________
Binary subnet mask: __________ . __________ . __________ . __________ -
What is the maximum number of subnets that can be created with this subnet mask?
-
What is the maximum number of useable subnets that can be created with this mask?
-
How many bits were left in the 4th octet for host IDs ?
-
How many hosts per subnet can be defined with this subnet mask?
-
What is the maximum number of hosts that can be defined for all subnets with this scenario (assuming you cannot use the lowest and highest subnet numbers and cannot use the lowest and highest host ID on each subnet) ?
-
Is 197.15.22.63 a valid host IP address with this scenario?
-
Why or why not ?
-
Is 197.15.22.160 a valid host IP address with this scenario?
-
Why or why not ?
-
Host "A" has an IP address of 197.15.22.126. Host "B" has an IP address of 197.15.22.129. Are these hosts on the same subnet?
