Assign a 60 host network using the ip block 192.168.1.0/24. Allow 0 and 1 subnets? Please can you help me out on how to assign this from the 1st host to the 60th host. Thanks..

@ mike: in your example 216.205.247.24/27 the /27 part represents a 27 bit subnet mask (i.e. 255.255.255.224) which would borrow 8 host bits from a class C IP address and give you 32 hosts per subnet.

So the subnet addresses would be 216.205.247.0, .32, .64, .96, .128, .160, .192, and .224. The IP address you listed (216.205.247.24) would fall in the first subnet (216.205.247.0) which would have a range of 216.205.247.1 – 216.205.247.30 (216.205.247.31 would be the broadcast address and cannot be assigned to a host)

Hope that helps!

how would go about doing this: use the address space 192.168.1.0/24

Vlan 15: needs space for 100 hosts?

Please correct me if I am wrong.

This IP address is a class C with a mast of 28 which means 4 bits of network and 4 bits of subnets.

128 64 32 16 8 4 2 1

1 1 1 1 0 0 0 0

Given the ip address 209.46.195.123/28

why would the network be 209.46.195.112

why would the 1st host be 209.46.195.113

why would the last host be 209.46.195.126

why would the b-cast be 209.46.195.127

Can you please explain. Thank you.

This post is excellent. I’m now using these instructions to teach a class. If you want some practice with instant feedback, try reading this post, then heading here:

You can generate examples and practice. Do this for an hour, and you’ll feel like an expert.
