How many IP addresses are in a 29?
For example, you would request a “/29” subnet from your ISP, and you would be provided with a subnet of 8 IP Addresses, 6 of which are usable – this is because 1 is the network address (the first IP) and one is the broadcast address (the last IP).

What is a 255.255 255.0 subnet?
A subnet mask of 255.255. 255.0 allows for close to 256 unique hosts within the network (since not all 256 IP addresses can be used). … This is the default subnet mask used by Class B networks and provides up to 65,536 IP addresses (256 x 256). The largest Class A networks use a subnet mask of 255.0.
What is the subnet mask of 192.168 1.0 24?

What is a 255.255 254.0 subnet?
255.255.254.0 = 1 bit less than 24 bits mask, so (256 x 2) – 2 hosts = 510. And to know if an ip address is good or not regarding a certain subnet..i do the following: Is 192.168. 1.64 – 255.255.
How many subnets and hosts per subnet can you get from the network 172.20 0.0 27?
172.20. 0.0 is subnetted by borrowing 12 bits from the host portion of the address (28 – 16 = 12). 4096 subnet and 14 hosts answer.
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 hosts are available 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 do you calculate the number of subnets?
To calculate the number of possible subnets, use the formula 2n, where n equals the number of host bits borrowed. For example, if three host bits are borrowed, then n=3. 23 = 8, so eight subnets are possible if three host bits are borrowed.
How many subnets are there?
How Many Hosts and How Many Subnets
| Address | 8.1.4.5/16 | 199.1.1.100/24 |
|---|---|---|
| Number of host bits | 16 | 8 |
| Number of subnet bits | 8 | 0 |
| Number of hosts per subnet | 216 – 2, or 65,534 |
28 – 2, or 254 |
| Number of subnets | 28 – 2, or 254 | 0 |

What subnet mask is represented by the slash notation 20?
The slash notation /20 represents a subnet mask with 20 1s. This would translate to: 11111111.11111111. 11110000.0000, which in turn would convert into 255.255. 240.0.
What is the maximum number of IP addresses that can be assigned to hosts on a local subnet?
Six hosts are the maximum number of hosts on this LAN, including the router interface. Out of the 8 addresses possible with the host bits, the first and the last address are for the subnet id and broadcast address respectively.
What is a 29 subnet?
/29 means that 29 of the 32 bits of the address are the netmask, therefore, only 3 bits are available for differentiating between computers.
How many usable hosts are in a 29 subnet?
For Class B Networks
| network | network mask | hosts |
|---|---|---|
| /count | possible | |
| 28 | 255.255.255.240 | 16 |

How do you find out how many IP addresses I have?
Try following steps:
- Type ipconfig (or ifconfig on Linux) at command prompt. This will give you the IP address of your own machine. …
- Ping your broadcast IP address ping 192.168. 1.255 (may require -b on Linux)
- Now type arp -a . You will get the list of all IP addresses on your segment.
How many host nodes are supported on a single Class C network?
This class defines a maximum of 2,097,152 (2 21 ) /24 networks. And each network supports up to 254 (2 8 -2) hosts. The entire class C network represents 2 29 (536,870,912) addresses; therefore it is only 12.5 % of the total IPv4.
How many host IDs were available in a class B network?
Class B (128.0. 0.0 to 191.255. 255.255) for general use. Class B addresses are for intermediate networks; they use 16-bit host addresses and 16-bit network addresses.
