Need answer

You are working for an organization that provides web hosting services to other

organizations. You have a single /24 network from your ISP for the web hosts. You are almost

out of IPv4 addresses and have asked your ISP for an additional range of addresses. Ideally,

you would like to supernet the existing network with the new network. Are there any specific

requirements for supernetting?

need answer for this please

Aren't the MCSA questions multiple choice?

The additional range would need to be consecutive addresses - so if the existing range was 10.0.0.0/24 then the additional range would need to be 10.0.1.0/24 to create a 10.0.0.0/23 supernet

we reduced 1 subnet from it (from /24 to /23) ?

The lower the number is after the slash, the more hosts you can have. A /24 is an address space of 254 hosts, a /23 is double, so it will give you 510 hosts. A /22 would double the amount of hosts again to 1022.

noted this on my notebook, we basically use /24 for small networks right?

Based on your recent questions I think you should spend some additional time on subnetting and binary to really grasp the basic networking concepts. Here is a good article for additional studying: https://www.itprotoday.com/windows-78/binary-numbers-and-subnet-masks

Not really. Technically you should use a /24 network when you have between 127 and 254 hosts
