The Internet Systems Consortium has stopped maintaining their DHCP client, which is standard on a lot of distros.
Debian has updated its documentation and now warns users to choose an alternative:
https://packages.debian.org/bookworm/isc-dhcp-client
On Debian Unstable, I was already forced to uninstall it in yesterday’s upgrade.
If you’re using network-manager, you don’t need to worry, since it includes its own dhcp client, but for others, this might be relevant.
On Arch, this concerns the dhcpd package:
https://wiki.archlinux.org/title/Dhcpd
On Arch, the client is in the
dhclient
package, which is generally also the name of the ISC DHCP client binary.dhcpcd
(DHCP Client Daemon) is not affiliated with the ISC and still appears to be under active development.I mentioned dhcpd (the ISC DHCP server demon), not dhcpcd, the unaffiliated DHCP Client demon.
