    I faced exactly the same problem on a recent new install of Debian
    11.

I decided to use systemd-networkd service and removed most of the stuff from /etc/network/interfaces

This is my /etc/systemd/network/wired.lan.network file (name arbitrary)

I also get an additional static IPv4 address

cat /etc/systemd/network/wired_lan.network
[Match]
Name=enp7s0
[Network]
DHCP=yes
Address=192.168.0.10/24
Gateway=192.168.0.1
DNS=192.168.0.4 192.168.0.5
Address= 2345:0425:2CA1::0567:5673:23b5/64
IPv6PrivacyExtensions=yes
IPv6AcceptRA=yes
Domains=lan exampledomain.com
[IPv6AcceptRA]



cat /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

source /etc/network/interfaces.d/*

# The loopback network interface
auto lo
iface lo inet loopback
