There are only 10 types of people in the world, those that understand binary 
and those that don't!

Yup, and yes, you should be very familiar with binary. It’s what everything is 
based on, afterall. ☺

Subject: Re: Expaning Subnet again

Just to get things right:
if i go with Subnet: 255.255.252.0 I can then have my range from:
192.168.0.0 -> 192.168.3.255 with
192.168.0.0 = Subnet Address and
192.168.3.255 = Broadcast Address.

And yes I did get the "Advanced Subnet Calculator", do I really need to count 0 
and 1, it was like 40 year ago I took Binary in school.

Anyhow thanks all for your help as usual.

Yes I have x.0 and x.256 excluded anyhow, and assume the brodcast is 
192.168.3.256 not 254, right.

Aside from the fact that you should not use 192.168.0.0 or 192.168.1.0
[1], you will at that point have a single subnet of 192.168.0.0 to
192.168.3.255, with 192.168.0.0 being your subnet address and
192.168.3.254 being your broadcast address.

[1] Too much consumer and other equipment uses those to /24 subnets as
their default, and people don't tend to change them. Thus, using them
is not a good idea, especially if you have people connecting via VPN
to your environment.
