I currently work at a school who have a /22 network assigned to them by the state school department. All the schools in the state are connected to each other through a WAN. The network address they got assigned is 10.135.164.0. My boss would like to implement a few VLANS but the problem is they want the 1st VLAN to be a specific IP range.
So far this is what I've planned:
The 1st VLAN is meant to support 100 hosts so i gave it a /25 subnet.
The 2nd VLAN will be the teachers and students VLAN and I gave them a /23 subnet
The 3rd VLAN is for VOIP, which I gave a /26 subnet
These 3 subnets fit easily in
There is also a Admin subnet which is small and uses a completely different subnet which doesnt need to be touched at all.
Now I know from studying CCNA you are meant to use biggest to smallest for VLANS, but the school system REQUIRES the servers, management IP's for switches, printers etc to use the 10.x.x.1 - 10.x.x.100 range.
So my question is, am I able to use the VLANS in this specific order:
VLAN 1: 126 hosts /25
VLAN 2: 510 hosts /23
VLAN 3: 62 hosts /26
What would the VLAN 2 and VLAN 3 subnet come out to be, can I just continue to VLSM as normal after the 1st subnet?
Subnet Name | | Size | Address | Mask | Dec Mask | Assignable Range | Broadcast |
VLAN 1
| | 126 | 10.135.164.0 | /25 | 255.255.255.128 | 10.135.164.1 - 10.135.164.126 | 10.135.164.127 |
VLAN 2
| | 510 | 10.135.164.128 | /23 | 255.255.254.0 | 10.135.164.129 - 10.135.
| |
VLAN 3
| | 62 | | /26 | 255.255.255.192 | | |
