What is the subnet mask for maximum number of hosts?
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.
What is the maximum number of IP address that can be assigned to hosts on a local subnet that uses the 255.255 255.240 subnet mask?
Class A
| Network Bits | Subnet Mask | Number of Hosts |
|---|---|---|
| /27 | 255.255.255.224 | 30 |
| /28 | 255.255.255.240 | 14 |
| /29 | 255.255.255.248 | 6 |
| /30 | 255.255.255.252 | 2 |
What is the maximum number of addresses in each subnet?
Creating and using subnets can help to keep your network organized and functional. Each IP address block can create 254 IP addresses, which allows 254 x 4 total IP addresses to be created for use in the network. This amounts to 1,016 IP addresses.
How many subnets are in a 20?
| Network Bits | Subnet Mask | Number of Subnets |
|---|---|---|
| /19 | 255.255.224.0 | 8 (6) |
| /20 | 255.255.240.0 | 16 (14) |
| /21 | 255.255.248.0 | 32 (30) |
| /22 | 255.255.252.0 | 64 (62) |
How to calculate the number of hosts in a subnet?
(Each bit in the subnet mask can be zero in a host or one in a host.) and on the question of maximum number of hosts then one must subtract the network ID from the local Broadcast address. Using the formula (2^11)-2 then we shall get 2046 to be the maximum number of hosts.
When is a subnet mask part of the network?
Whenever a bit in a binary subnet mask is 1, then the same bit in a binary IP address is part of the network, not the host. Since the octet 255 is 11111111 in binary, that whole octet in the IP address is part of the network.
Where can I find the subnet mask cheat sheet?
Subnet Mask Cheat Sheet Addresses Hosts Netmask Amount of a Class C /30 4 2 255.255.255.252 1/64 /29 8 6 255.255.255.248 1/32 /28 16 14 255.255.255.240 1/16 /27 32 30 255.255.255.224 1/8
How to figure out the CIDR notation for a subnet mask?
For instance, the /24 in 192.168.0.101/24 is equivalent to the IP address 192.168.0.101 and the subnet mask 255.255.255.0. To figure out the CIDR notation for a given subnet mask, all you need to do is convert the subnet mask into binary, then count the number of ones or “on” digits.
