Dear Maintainer,
* What led up to the situation?
I wanted systemd-networkd to select the first address (zero) from the ipv6
prefix that was delegated to me. My provider (Vodafone Kabel / Germany) offers
me a /56 prefix via prefix delegation.
My .network file looks like this:
[Match]
Name=enp1s0
[Network]
IPv6AcceptRA=yes
DHCP=yes
DHCPPrefixDelegation=yes
[DHCPv6]
PrefixDelegationHint=::/56
UseDNS=no
UseAddress=no
[DHCPPrefixDelegation]
Token=static:::
* What exactly did you do (or not do) that was effective (or
ineffective)?
I tried to set the "Token=" option in the [DHCPPrefixDelegation] section of my
.network file as follows:
[DHCPPrefixDelegation]
Token=static:::
* What was the outcome of this action?
The resulting ipv6 address is selects via eui64 instead of static.
So i get a address like this 2001:db8::a60:6eff:feda:858a/64
* What outcome did you expect instead?
I expected the address to be zero. More like this: 2001:db8::/64 (which is a
valid ipv6 address).
I also tried the following values:
Token=static:::0 # does not work
Token=:: # does not work
Token=static:::0000 # does not work
Token=static:::1 # works as expected, but is not what i want, address would be
2001:db8::1/64
