Does anyone knows how to use /48 ipv6 subnet from anynode.net?

serveradministrator

I got a new VPS from anynode.net and they gave me a /48 ipv6 block. This is what my interfaces looks like on Debian

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

# The loopback network interface
auto lo
iface lo inet loopback

# The normal eth0
allow-hotplug eth0
iface eth0 inet dhcp

# Additional interfaces, just in case we're using
# multiple networks
allow-hotplug eth1
iface eth1 inet dhcp

allow-hotplug eth2
iface eth2 inet dhcp

# Set this one last, so that cloud-init or user can
# override defaults.
source /etc/network/interfaces.d/*

This is something new to me as I always generated IPv6 in control panel for years. Is there any user who can share the config file with me so that I can use the subnet. There are no IPv4 or IPv6 listed or any gateway information. IPv6 is not working right now. Also I would like to use Wireguard later on, it would be nice to get some information on how to get a subnet for Wireguard

/etc/netplan/netplan.yaml

network:
    version: 2
    ethernets:
        eth0:
            addresses:
            - 2001:db8::YOURIP/48
            - 2001:db8::YOURIP/48
            - 2001:db8::YOURIP/48
            gateway6: 2001:your:gateway
            match:
                macaddress: interface:mac:address # do 'ip a' to show mac
            set-name: eth0

Thanks, how can I make couple of /64 subnets to use from 2605:1111:1111::/48

oh sorry, you are on debian with legacy style etc/network/interfaces

you can probably add something like post-up ip -6 a 2605:111::/48 dev eth0

you don't need to make, just end in /48

serveradministrator

Yes I use Debian 10

/etc/network/interfaces for an address from a /48 block. Check the CP (e.g. SolusCP) for what values to insert.

iface eth0 inet6 static
   address 2602:xx:yy::1
   netmask 48
   gateway 2602:gateway

For WireGuard with IPv6 addresses allocated from the block, you need to check if your provider offers routed ipv6 addresses (you are in luck) or just on-link ipv6.

1. If routed, just assign the ipv6 address in the WireGuard config.
2. If on-link, you have to ask your provider to disable ebtables (assuming kvm). You will then have to enable ndp proxy and proxy your WireGuard assigned ipv6 address through eth0, so that your provider’s router is able to route the ipv6 data.
