Does ESXi have to have IP address of virtual machine's segment?

I'm wondering if ESXi has to have IP address of virtual machine's segment or not.

This is the situation.

There are 2 ESXi and each ESXi has VMs.

Only VMs need to communicate each other, not between VMs and ESXi.

What if NW settings are like below.

Can VMs communicate each other with eth2?

[ESXi1]

vSwitch0: 192.168.1.1/24

vSwitch1: no IP address

[ESXi2]

vSwitch0: 192.168.1.2/24

vSwitch1: no IP address

[VM1]

eth1: 192.168.1.11/24

eth2: 192.168.10.11/24

[VM2]

eth1 192.168.1.12/24

eth2 192.168.10.12/24

Thanks.
