Update the networking docs to reflect the default bind-ip change from 0.0.0.0 to :: in Restate Server 1.7.0, which enables dual-stack (IPv6 and IPv4) listening and IPv6-only environments. Addresses #286. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Maybe this is a bit too detailed in terms of what's interesting to users. @gvdongen do you have a recommendation for whether to keep or remove this section?

You could put it as a collapsed section and call it "Advanced: Dual-stack and IPv6" and put it at the bottom of the section.
You can collapse it with <Accordion title="..."> ... </Accordion>
Explain that :: accepts IPv4 connections as IPv4-mapped IPv6 addresses when the IPv6 stack is present, and document that a kernel with IPv6 disabled fails to bind (no automatic fallback), requiring bind-ip = 0.0.0.0. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Updates the networking documentation to reflect dual-stack support, addressing #286 (which tracks restatedev/restate#4529).
Restate Server 1.7.0 changed the default
bind-ipfrom0.0.0.0(IPv4 only) to::(IPv6 unspecified), which creates a dual-stack socket accepting both IPv4 and IPv6 connections on most systems.Changes to
docs/server/networking.mdx:bind-ipdefault to::in the global options table and per-service text.net.ipv6.bindv6only=1edge case, and how to restore IPv4-only behavior.[::]:....--bind-ip=::.Details verified against the restate source (
crates/types/src/net/address.rsdefault::) and the 4529 release note. The change ships in v1.7.0.Note: this targets
restate-1.7, so merging will not auto-close #286 (that only happens on merge tomain).🤖 Generated with Claude Code
