If I limit total IPv4 addresses to 181 or less, it works. But anything larger than 181 fails. Below are my configurations and error logs. **/etc/netplan/10-ens3.yaml** ``` network: version: 2 renderer: networkd ethernets: ens3: dhcp4: no addresses: - 140.XX.XX.XX/23 - 103.XXX.XX.1/24 - 103.XXX.XX.2/24 - CONTINUED IP ADDRESS UPTO BELOW ... - 103.XXX.XX.254/24 gateway4: 140.XX.XX.X nameservers: addresses: [1.1.1.1, 1.0.0.1] routes: - to: 169.254.0.0/16 via: 140.XX.XX.X metric: 100 ``` The above config works if I run `netplan apply` but when I reboot, it does not work. **networkctl** ``` IDX LINK TYPE OPERATIONAL SETUP 1 lo loopback carrier unmanaged 2 ens3 ether routable failed 2 links listed. ``` **/etc/systemd/system/systemd-networkd.service.d/override.conf** ``` [Service] Environment=SYSTEMD_LOG_LEVEL=debug ``` **systemctl status systemd-networkd.service** ``` ● systemd-networkd.service - Network Service Loaded: loaded (/lib/systemd/system/systemd-networkd.service; enabled-runtime; vendor preset: enabled) Drop-In: /etc/systemd/system/systemd-networkd.service.d └─override.conf Active: active (running) since Thu 2020-09-10 19:46:58 UTC; 1min 36s ago Docs: man:systemd-networkd.service(8) Main PID: 346 (systemd-network) Status: "Processing requests..."
