Networking, mutually exclusive subnets

Posted on 2012-09-19

I want to put 4 nodes into 2 separate subnets.

Subnet 1     /29  /29

Subnet 2     /29  /29

Open in new window

The subnet calculator reports the following:  /29

Hosts: -
Broadcast:  /29

Hosts -     
Broadcast:  /29
Hosts: -   
Broadcast:  /29

Hosts: - 

Open in new window

will this following IPs in subnet 1 only be able to communicate with each other without going to a router     /29  /29

Open in new window

and will the same be true for the nodes in subnet 2     /29  /29

Open in new window

Am I missing anything.  Any potential problems in this scenario ?

    Accepted Solution

    These nodes are in four different subnets. None of them will be able to communicate with any of the three others without routing.

    As said, you have FOUR subnets listed.

    A subnet is a contiguos address space of IP addresses defined by the mask. you can not have 2 distinct ranges and call them a subnet just because you want them to be one.
    You need to route ALL 4 subnets.
