Is there a way to force the DHCP client on Debian/Ubuntu to renew its lease ahead of time? For example, if the lease duration is a week, but you want the client to refresh the list of DNS servers immediately.
Will "netplan apply" do it? Or "systemctl restart systemd-networkd"? That seems extreme; I don't want a network/service interruption -- things like IP address/netmask/gateway won't change in the case I'm thinking of but other configuration details may need updating. Mind you, I have little idea what all systemd-networkd is responsible for.
In Windows, for example, you'd run "ipconfig /renew". Is there an equivalent for Debian/Ubuntu?
