Public bug reported: Hi all,
We want to set up an IPv6-only network in a lab, and some Ubuntu ( release >=18.04) needs to be configured according to the networking requirements. I found a Netplan doc about disabling ipv6 by editing the Netplan YAML file: https://github.com/canonical/netplan/blob/main/doc/netplan-tutorial.md#editing-netplan-yaml-files-to-disable-ipv6 === When you finish, the whole configuration in second-interface.yaml should look like this: network: version: 2 ethernets: enp6s0: dhcp4: true accept-ra: false link-local: [] === can I use the same way to disable IPv4? e.g. network: version: 2 ethernets: eth0: dhcp4: false dhcp6: true accept-ra: false link-local: [ipv6] Or are there other ways to disable ipv4 on Ubuntu? In addition, Ubuntu 18.04 uses ifupdown with /etc/network/interfaces to configure the networking e.g. === iface lo inet loopback auto lo auto eth0 iface eth0 inet manual iface eth0 inet6 dhcp netmask 16 accept_ra 1 autoconf 1 === Can I add 'iface eth0 inet manual' in this file to disable IPv4? Thanks, Thanks, ** Affects: netplan.io (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2070434 Title: Configurate a IPv6 only and IPv4 disabled networking by netplan To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/netplan.io/+bug/2070434/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
