i can't reproduce this, and your log output looks like you have are
having problems with your ipv6 configuration, not ipv4. you'll need to
attach the full journal log if you still have this problem

Title:
network configuration failed on reboot
Status in systemd package in Ubuntu:
Incomplete
Bug description:
This issue was reported at
https://github.com/systemd/systemd/issues/17012
**Used distribution**
> Ubuntu 20.04.1 LTS
**systemd version the issue has been seen with**
> 245.4-4ubuntu3.2
**Issue details**
I configured 255 IPv4 address (including primary IP) using netplan but when
the server restart, it time out on configuring the interface. 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**
