- What class is their original network? What is their "natural" subnet mask?
(Express this several different ways).
Class C: 255.255.255.0/24 or
200.10.10.0
255.255.255.0
- How many bits to borrow for this subnetting scheme?
2? >= 12
- What is the subnet mask for this subnetwork scheme?
255.255.255.240/28 11111111.11111111.1111111.11110000/28 subnet bits in blue
- What is the maximum number of hosts can each subnet have? How many can be used as host addresses?
max hosts/subnet: 2^4 = 16, usable hosts/subnet: 14
- List each of the individual subnet (network) addresses
in dotted decimal and in binary (especially the last octet). Make sure to denote ENP (extended network prefix)
length. Subnet bits in blue.
