## What subnet is 192?

Subnet Mask Information

Number of Addresses | Number of Bits | Mask |
---|---|---|

16 K |
14 | 255.255.192 |

32 K | 15 | 255.255.128 |

64 K | 16 | 255.255 |

128 K | 17 | 255.254 |

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

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 hosts can you have per subnet?

Hosts per subnet: 3 bits are left to identify the host therefore the total number of hosts per subnet is 2 to the power of 3 minus 2 (1 address for subnet address and another one for the broadcast address)(2^3-2) which equals to **6 hosts per subnet**.

## How many hosts can be accommodated in a 24 subnet?

Class A

Network Bits | Subnet Mask | Number of Hosts |
---|---|---|

/22 | 255.255.252.0 | 1022 |

/23 | 255.255.254.0 | 510 |

/24 | 255.255.255.0 | 254 |

/25 | 255.255.255.128 | 126 |

## How many host addresses are available in the 128 network?

/ 24 | 256 | 254 |

/ 23 | 512 | 510 |

## How do you calculate hosts per subnet?

To calculate the number of possible hosts per subnet, **use the formula 2h – 2, where h equals the number of host bits**. The reason two addresses must be subtracted is because of the network address and the broadcast address.

## How many hosts are allowed in the Class C IP address?

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**.

## How many hosts are in a 8?

In this example, there are 8 network bits because the address is in a Class A network, 8.0. 0.0. There are **16 host** bits because, when you convert 255.255.
