Issue "Public IP Address" field - How to disable or change

[BigD213]

Server operating system version

Ubuntu 20.04.4 LTS

Plesk version and microupdate number

Plesk Obsidian Version 18.0.45

I have to keep logging in to clear this entry under "Public IP Address".

I have a unique LAN configuration that requires that this field is clear. I have also tried setting it to the LAN IP. A few days later, it automatically changes itself.

1 - How do I prevent this field from automatically updating itself?
2 - How can I clear this field from the command line?
3 - How can I disable this feature entirely?

- Identify the interface on which the Public IP address is located:

# ip a
2: venet0: <BROADCAST,POINTOPOINT,NOARP,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN
link/void
inet 192.0.2.2/32 brd 10.39.81.154 scope global eth0
inet 203.0.113.2/8 scope global eth0:1

- Remove the IP address from the interface:

# ip addr del 203.0.113.2/8 dev eth0

- Remove the old IP address:

# plesk db "delete from IP_Addresses where ip_address='203.0.113.2'"
