Package: systemd Version: 252.19-1~deb12u1 Severity: normal Tags: ipv6 X-Debbugs-Cc: fmu+deb...@never-afk.deDear 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
The Debian package does not ship any patches in that regard. It would thus be best if you raise this issue directly upstream athttps://github.com/systemd/systemd/issues if you can reproduce it with v254 or v255 (you can pull v254 from bookworm-backports).
