nixos-infect emitted defaultGateway6.address="" and ipv6.routes=[{address="";
prefixLength=128}] for this v4-only Hetzner instance, so network-addresses-eth0.service
failed at boot ("ip route add /128 ... any valid prefix is expected rather than /128").
The box has no real IPv6 (link-local only, kernel-managed), so remove the empty IPv6
gateway, address, and route. IPv4 unchanged.

# This file is server-specific: the IP, gateway, and MAC address are tied to a

# particular Hetzner instance. When provisioning a new server:
|
|
# 1. After `terraform apply` + nixos-infect completes, run:
|
|
# ssh root@<new-ip> 'cat /etc/nixos/networking.nix'
|
|
# 2. Replace this file's contents with the output and commit.
|
|
# 3. Then: `nixos-rebuild switch --flake .#cc-ci-hetzner --target-host root@<new-ip>`
