Description

In docs/pages/cloud/dedicated/network_ipv6/guide.en-ca.md it says every dedicated server gets a /64 IPv6 block, but on suggested Debian configuration it has net_mask 128.
I've checked my Debian servers (using OVH/Kimsufi's image) and my server IPv6 block is configured to /128 after a ip -6 addr list dev enp1s0.
The docs also does not use Debian's systemd configuration (systemd is the default init system on Debian since Jessie).
Between my servers inside OVH network I can ping the IPv6 addresses, but can't connect from outside using IPv6. What should I do?

Research direction

Start with docs/pages/cloud/dedicated/network_ipv6/guide.en-ca.md and compare its /64, net_mask 128, and Debian configuration guidance with the reported ip -6 addr output. Verify the correct prefix and current systemd-based Debian setup, including external IPv6 reachability. Done means the guide accurately explains the configuration and resolves the discrepancy.
