New page

[https://github.com/ifupdown-ng/ifupdown-ng ifupdown-ng] is a network device manager which is backwards compatible with traditional ifup and ifdown as used on Debian and Alpine systems, while solving many design deficits with the original approach through robust error handling and the use of a dependency-solver to determine interface bring-up order.

== Installation ==

The {{pkg|ifupdown-ng}} package is installed as part of {{pkg|alpine-base}} package and provides necessary tools for managing network configuration in Alpine Linux.

== DHCP support ==

ifupdown-ng supports {{ic|udhcpc}} from [[BusyBox]], {{pkg|dhcpcd}} and dhclient. Of these, only dhcpcd can interact with both DHCP and DHCPv6 from the same process, which ifupdown-ng requires. Thus the IPv4 DHCP configuration given on this page will also result in the use of DHCPv6, but only if the {{pkg|dhcpcd}} package is installed. The ifupdown-ng scripts prioritize dhcpcd over udhcpc as per {{path|/usr/libexec/ifupdown-ng/dhcp}} script.
{{Note|The third dhcp client {{pkg|dhclient}} is no longer available in Alpine Linux since [[Release_Notes_for_Alpine_3.21.0#ISC_DHCP|v3.21]]}}

The availability of {{pkg|ifupdown-ng}} package can be checked via the command {{ic|ifquery --version}}.
