Networking, mutually exclusive subnets

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 ?

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.
