Air-gap:
- DynamicRecord.refreshAll() called getPublicIp() (api.ipify.org,
icanhazip.com, ifconfig.me) every 4h on a timer regardless of
whether any dynamic records were configured -- the one background
call in the repo not actually gated by feature use. Now skips the
lookup entirely when there's nothing to refresh.
- Removed the stray, unauthenticated GET /test page (a leftover
jq-repeat demo) that loaded jQuery + Mustache from external CDNs.
- Removed a dead IE<9-only html5shim script tag pointing at a domain
that no longer resolves.
Docs:
- New GET /docs (index) and /docs/:slug routes render this project's
own README, DEPLOYMENT, api.md, and docs/*.md server-side via
marked (new dependency) -- so the documentation is readable from
the running app with no route to GitHub Pages, where it otherwise
only lives. Public, no auth, same tier as the health endpoint.
- .dockerignore/Dockerfile updated: docs/, DEPLOYMENT.md, and
nodejs/api.md were previously excluded from the image entirely
("served via GitHub Pages, not from the image") -- now copied in
alongside README.md/tos.md-style, since they're needed at runtime.
The Host and Last-updated columns were blank because they relied on a jq-repeat
parseData hook that the rest of the app doesn't actually use for display (working
rows derive dates from the .momentFromNow class, not parseData).
- Derive fqdn server-side via DynamicRecord.toJSON so it flows through both the
REST list and websocket payloads; the template uses {{fqdn}} directly.
- Render last-updated with the .momentFromNow class (data-date) like the rest of
the app instead of a parseData-computed string.
- apply() now clears last_status on success so the UI only surfaces real errors.
- Redesign the section: prominent public-IP badge, cleaner add form, and a
Bootstrap list-group of records (fqdn, IP badge, "updated N ago", inline error)
with outline refresh/remove buttons.

For deployments on WAN DHCP, operators can declare A records in the DNS section
that the app updates to this box's current public IP every 4 hours (and
immediately on create).
- utils/public_ip.js: getPublicIp() queries external echo services (ipify +
fallbacks, configurable) with pure isIPv4/extractIp helpers.
- utils/dns_records.js: pure planARecordUpdate() reconciliation decision.
- models/dns_provider.js: Domain.upsertARecord(name, ip) — provider-agnostic
upsert via getRecords + deleteRecordById + createRecord (createRecord alone is
not a reliable cross-provider upsert). Apex ('@') handling added to each
provider (CloudFlare uses the domain name, Porkbun an empty name, DigitalOcean
'@') via a new DnsApi.apexName().
- models/dynamic_record.js: DynamicRecord model (deterministic id per host,
apply()/refreshAll()), registered + ModelPs-wrapped for live UI updates.
- services/dynamic_dns.js + conf: 4h scheduler mirroring host_scheduler.
- routes/dns.js: /dynamic CRUD + /dynamic/ip, gated to domain managers/admins.
- views/dns.ejs: "Dynamic A Records (WAN IP)" card with add form + list.
- test/unit/dynamic_record.test.js: public-IP parsing + reconciliation logic.
Verified end-to-end against a live Porkbun domain (create, idempotent, IP-change,
cleanup) plus unit suite (111 pass).
