What is a 255.255 0.0 subnet?
It is a 32-bit number that distinguishes each octet in the IP address. For example, as depicted in Table 4.9, 255.255. 0.0 is a standard Class B subnet mask, since the first two bytes are all ones (network) and the last two bytes are all zeros (host). 240.0 (4 bits of subnet; 12 bits of host) can also be used.
How many subnets does a 22 have?
Network Bits | Subnet Mask | Number of Subnets |
---|---|---|
/22 | 255.255.252.0 | 64 (62) |
/23 | 255.255.254.0 | 128 (126) |
/24 | 255.255.255.0 | 256 (254) |
/25 | 255.255.255.128 | 512 (510) |

What does the mask 255.255 0.0 tell you?
A subnet of 255.255. 0.0 would give you lots of hosts (approx 216) and 256 networks.
What does 24 mean in ip address?
This is called “slash notation”. There is a total of 32 bits in IPv4 address space. For example, if a network has the address “192.0. 2.0/24”, the number “24” refers to how many bits are contained in the network. From this, the number of bits left for address space can be calculated.
