Mac Client assign weird IP

### Describe the Bug

My client got a network address 100.90.128.0 instead of any other IP like 100.90.128.5

{
"agent" : "Pangolin macOS",
"connected" : true,
"networkSettings" : {
"dns_servers" : [
"100.96.128.1"
],
"ipv4_addresses" : [
"100.90.128.0"
],
"ipv4_included_routes" : [
{
"destination_address" : "100.96.128.0",
"subnet_mask" : "255.255.240.0"
}
],
"ipv4_subnet_masks" : [
"255.255.240.0"
],
"mtu" : 1280
},
"orgId" : "masjoy",
"registered" : true,
"terminated" : false,
"version" : "0.8.1"
}

### Environment

- OS Type & Version: (e.g., Ubuntu 22.04)
- Pangolin Version:1.18.2
- Gerbil Version:
- Traefik Version:
- Newt Version:
- Client Version: 0.8.1

### To Reproduce

I just installed the client nothing more

### Expected Behavior

Got an addressable point to point IP

Start by reproducing the installation on the Pangolin macOS client at version 0.8.1 and inspect the reported networkSettings, especially the assigned IPv4 address and subnet mask. Compare the result with the expected addressable point-to-point IP and document a test or reproduction that confirms the corrected assignment.
