8. How does classless interdomain routing (CIDR) help reduce waste of IP addresses? a. CIDR uses a subnetting method also called variable length subnet masking. b. CIDR uses a subnetting method that divides between network bits and host bits anywhere, not just between octets. c. CIDR uses Network Address Translation. d. CIDR converts between IPv4 and IPv6.

b

1. Specify the correct order of steps necessary to calculating an IPv4 subnet mask. a. Calculate the subnet mask by adding the network and subnet bits in binary form and converting the binary value to decimal. b. Take the least significant subnet bit and the host bits, in binary form, and convert them to a decimal value. c. Determine how many subnet identifier bits you need to create the required number of subnets. d. Subtract the subnet bits you need from the host bits and add them to the network bits. e. Increment the network identifier (including the subnet bits) by the decimal value you calculated to determine the network addresses of your new subnets.
