How many hosts can class a hold?
The InterNIC assigns only the first byte of a class A number. Use of the remaining three bytes is left to the discretion of the owner of the network number. Only 127 class A networks can exist. Each one of these numbers can accommodate up to 16,777,214 hosts.
How many hosts can a class A subnet have?
Subnet a Class A network with ease
Mask | Prefix | Hosts |
---|---|---|
255.254.0.0 | (/15) | with 131,070 hosts each |
255.255.0.0 | (/16) | with 65,534 hosts each |
255.255.128.0 | (/17) | with 32,766 hosts each |
255.255.192.0 | (/18) | with 16,384 hosts each |
How do you calculate the number of hosts in Class A?
To find the maximum number of hosts, look at the number of binary bits in the host number above. The easiest way to do this is to subtract the netmask length from 32 (number of bits in an IPv4 address). This gives you the number of host bits in the address.
How many hosts does a network have?
The formula to determine how many hosts can operate on a network is 2n-2, where n is the number of 0 bits in the subnet mask. A subnet mask has 32 bits. If the CIDR notation is /27 it indicates that there are 5 bits left to create subnets.
How many hosts can a Class C network have?
A Class C address consists of a 24-bit network address and an 8-bit local host address. The first three bits in the network address indicate the network class, leaving 21 bits for the actual network address. Therefore, there are 2,097,152 possible network addresses and 256 possible local host addresses.
What is the maximum number of hosts that can be attached to a network in the Classful ipv4 address?
254
Thus, for a Class C address with 8 bits available in the host field, the maximum number of hosts is 254. Today, IP addresses are associated with a subnet mask.
How many hosts are in a 24 subnet?

/ 25 | 128 | 126 |
/ 24 | 256 | 254 |

How many hosts does a 24 network have?
Subnet Mask Cheat Sheet
Addresses | Hosts | |
---|---|---|
/25 | 128 | 126 |
/24 | 256 | 254 |
/23 | 512 | 510 |
/22 | 1024 | 1022 |
How many hosts could the network support?
You need to create 5 sub networks each network has a maximum of 10 hosts. We can only use the first 8 bits for out subnets as these 8 bits have been allocated as host addresses. So Subnet masks of 255.255. 255.224 and 255.255.
How many networks are in a class A?
126 networks
The default subnet mask for Class A IP address is 255.0. 0.0 which implies that Class A addressing can have 126 networks (27-2) and 16777214 hosts (224-2).
