subnets

[surfer100]

I think what i am asking is misunderstood (it's my fault) but it is not my intention to make a network plan but only i cannot understand what i am thinking is not goiing to work.

Example:
we want to make 4 vlan's with each its own subnet (all connecting together thru switches, each port is configured for the vlans), routing is handles by the switches, but then it is only a example:


vlan 2 - 10.3.0.0/24 - adresses thrue dhcp: 10.3.0.1 / 10.3.0.254
vlan 3 - 10.3.0.0/22 - 10.3.0.1 / 10.3.7.254
vlan 4 - 10.3.8.0/22- 10.3.8.1 / 10.3.8.254
And i can give devices a static ip between the ranges mentioned.
so vlan 3 starts with ipnumber 10.3.0.1 and some devices are getting 10.3.4.220, 10.3.4.244, 10.3.6.22 etc etc between 10.3.0.1 and 10.3.7.254
vlan 4 can have the ipnumbers: 10.3.8.22, 10.3.8.150, 10.3.7.220 etc etc.

So if the network is 10.3.0.0/16 the vlans and subnets can have about 65000 adresses.

This is what i mean vlan 3 would not deliver the ipadress: 10.3.2.20 but only from 10.3.8.1 and bove until 10.3.8.254

am i correct?

10.3.0.0/22 gives you 1024 IP addresses

yet 10.3.0.1 to 10.3.7.254 gives you 2046 addresses and you have to use /21

They conflict with each other.

Find IP addressing tutorial on the web or youtube. I'm done.
