`internal/ptr` asks Google, Cloudflare, AdGuard and Quad9 in turn, 2 seconds in all per address. It keeps answers in memory and writes them through to `cache.db`, opened by the new `internal/cachedb`. A reserved address is not sent to the resolvers. The cache holds at most 250,000 addresses.
Judgement calls:
- Each resolver gets an equal share of the time left, so a hung resolver does not use up the 2 seconds.
- The negative TTL is the smaller of the SOA minimum and the SOA's own TTL (RFC 2308).
- Names that are not host names are dropped, as `net.Resolver.LookupAddr` does.
Model: opus-5-5
The daemon's database is db.sqlite with its -wal and -shm files, which
the .db patterns in .dockerignore and .gitignore did not match, so a
database left in the clone shipped in the image's source archive.
.dockerignore now also excludes the logs and the .exe, .dll, .so and
.dylib files .gitignore already ignores. A test opens a database and
checks that .dockerignore has an any-depth pattern for each of its
files.

Takes .golangci.yml, .dockerignore, .gitignore, .editorconfig, the
workflow and REPO_POLICIES.md from sneak/prompts 0653579, with this
repository's own entries after the shared content. Lint (golangci-lint
v2.14.0) and test are Dockerfile phases that script/lint and script/test
build alone with a new CACHEBUST value, keeping Go's and golangci-lint's
caches; the image build depends on both. make fmt and make fmt-check also
format the markdown with prettier, pinned in yarn.lock. The agent
guidance moves to AGENTS.md. The Go code is fixed for what the new
configuration finds, and the AS and prefix detail reads now return the
rows' error after their loops.
Model: opus-5-5
- Move schema from database.go to schema.sql
- Use go:embed to include schema at compile time
- Add 'out' debug file to .gitignore
This makes the schema more maintainable and easier to review.
- Created bgp_peers table to track all BGP peers
- Added PeerHandler to update peer last seen times for all message types
- Removed verbose BGP keepalive debug logging
- BGP keepalive messages now silently update peer tracking
Refactor HTML templates to use go:embed
- Created internal/templates package with embedded templates
- Moved status.html from inline const to separate file
- Templates are parsed once on startup
- Server now uses parsed template instead of raw string
Optimize AS data embedding with gzip compression
- Changed asinfo package to embed gzipped data (2.4MB vs 12MB)
- Updated Makefile to gzip AS data during update
- Added decompression during initialization
- Raw JSON file excluded from git
- Created pkg/asinfo with embedded AS data from ipverse/asn-info
- Provides fast lookups by ASN with GetDescription() and GetHandle()
- Includes Search() functionality for finding AS by name/handle
- Added asinfo-gen tool to fetch and convert CSV data to JSON
- Added 'make asupdate' target to refresh AS data
- Embedded JSON data contains 130k+ AS entries
- Added comprehensive tests and examples
- Connects to RIPE RIS Live stream to receive real-time BGP updates
- Stores BGP data in SQLite database:
- ASNs with first/last seen timestamps
- Prefixes with IPv4/IPv6 classification
- BGP announcements and withdrawals
- AS-to-AS peering relationships from AS paths
- Live routing table tracking active routes
- HTTP server with statistics endpoints
- Metrics tracking with go-metrics
- Custom JSON unmarshaling to handle nested AS sets in paths
- Dependency injection with uber/fx
- Pure Go implementation (no CGO)
- Includes streamdumper utility for debugging raw messages
