VLSM on a /24 network

[Ruterford]

Hi, i have a network of 192.168.11.0/24 that is needed to be subnetted to one /26 network and two /30 networks. I want to keep all the rest of available hosts after subnetting to be available in the largest network blocks possible for future use. So I am planning to do vlsm like this

192.168.11.128 /26 for /26 network with 62 hosts, then I am planning to pick the least available subnets for /30 allocation

192.168.11.248/30 and 192.168.11.252/30

This way I think i will have better allocation of the subnetted hosys for future use. Like i will be able to go for

192.168.11.0/25

192.168.11.128/26 - which I already have

192.168.11.192/27

192.168.11.224/28

192.168.11.240/29

And

192.168.11.248/30

192.168.11.252/30

Is it a correct strategy taking into account consuming the larger the better ip blocks for future use? Or maybe I should just pick next available sibnet after /26 like going 128-64-2-2 instead of 128-64-32-16-8-4-4 or start from beginning of the network like 64-2-2?

Thanks!

It will work fine.  You can also do this:

your first subnet for your hosts:

192.168.11.0/26

then all the /27,28,30s

192.168.64.0/27

192.168.96.0/28

192.168.112.0/29

192.168.11.120/30

192.168.11.124/30

for future use

192.168.11.128/25

This way your first and last block is for hosts
