Your question: How many host IDs Do you always lose per network?

How many possible host IDs Do you always lose per network 8?

Remember that you always lose two host IDs per network. So, if a /24 network has two to the eight or 256 potential hosts, you really only have 256 minus two, or 254 available IPs to assign.

How many Host IDs are there?

A Class A network can support approximately 224 hosts, which works out to 16,777,216 hosts. A Class C network can support, on the other hand, can provide host IDs for only a small number of hosts (approximately 28 hosts, or 256), but many more combinations of network IDs are available in the Class C format.

How many hosts can a network have?

Class A Network (/ 8 Prefixes)

Each network supports a maximum of 16,777,214 (2 24 -2) hosts per network. You must subtract two because the base network represents host “0”, and the last host on the network is actually used for 1s (“broadcast”) and may not be assigned to any host.

How many network addresss are there in Class A?

IP address classes

Class Leading bits Number of networks
Class A 128 (27)
Class B 10 16,384 (214)
Class C 110 2,097,152 (221)
Class D (multicast) 1110 not defined

How many subnets and hosts per subnet can you get from the network?

255.255. 240.0 is a /20 subnet mask, therefore there are 4 borrowed bits (from the 3rd octet). Number of hosts on each subnetwork = (2 to the power 4) – 2 (i.e. 4 bits in host portion of address), which gives 14.

How many subnetworks and hosts are available per subnet If you apply a 27?
