IPv6 Tools

IPv6 policy enforcement and tooling for the hyperpolymath ecosystem.

This monorepo consolidates two adjacent IPv6 utilities into a single operational unit (shared CI, shared license, shared dependency state).

Components

ipv6-only/

IPv6-only network policy. Enforces that an environment (a node, a namespace, a deployment) does not fall back to IPv4 — surfacing mis-configurations rather than letting them degrade silently. See the directory’s own README for invocation.

ipv6-site-enforcer/

Site-level enforcement tool. Validates that a public-facing site serves IPv6 correctly (AAAA records, IPv6 socket bind, HTTP-over-IPv6). Suitable for periodic CI / monitoring use.

The two pair naturally: ipv6-only enforces locally, ipv6-site-enforcer enforces externally.

Quickstart

git clone git@github.com:hyperpolymath/ipv6-tools.git
cd ipv6-tools

# ipv6-only:
cd ipv6-only/ && just build && just test

# ipv6-site-enforcer:
cd ../ipv6-site-enforcer/ && just build && just run -- example.com

Status

• Licence: MPL-2.0. (Migrated from PMPL-1.0-or-later 2026-05-26 per the estate licence-debt audit, hyperpolymath/standards#196.)

• Estate role: infrastructure tooling — consumed by deployment workflows where IPv6 readiness is a hard requirement.

• Audit findings: see docs/tech-debt-2026-05-26.md if present (added by the 2026-05-26 estate tech-debt scan).

Contributing

See CONTRIBUTING.md. GPG-signed commits required.
