+# whatismyip
+
+Single-binary Go service: HTTP/TLS/QUIC server that returns the client's IP, geolocation, ASN, headers, TCP port scan, and DNS discovery. Uses [gin](https://github.com/gin-gonic/gin) + [httprouter](https://github.com/julienschmidt/httprouter). Requires Go >= 1.25.
+
+## Commands
+
+```sh
+make build                                           # CGO_ENABLED=0 -> ./whatismyip (GOOS/GOARCH for cross-compile)
+make build-all                                       # cross-compile all 5 platforms into dist/
+make unit-test                                       # go test -count=1 -race -short -cover ./...
+make integration-test                                # requires Docker; runs integration-tests/ module
+make test                                            # unit-test + integration-test
+make lint                                            # gofmt -l + golangci-lint + shadow (auto-installs tools)
+make docker-build                                    # local single-arch build (root Dockerfile)
+make docker-run                                      # builds dev image + runs with test DBs, ports :8080 :8081 :9100
+```
+
+**Order and quirks**: `lint -> unit-test -> integration-test`. Integration tests use testcontainers-go (needs Docker). They are a separate Go module with its own `go.mod` — run from the `integration-tests/` directory. They use `test/Dockerfile` (distinct from the root `Dockerfile`).

+```
+
+## Key facts
+
+- **DNS discovery**: enabled via `-resolver test/resolver.yml`. The resolver is an authoritative DNS server answering for a subdomain. Clients prove their DNS provider by resolving `<uuid>.dns.<domain>`.
+- **Geo**: both `-geoip2-city` and `-geoip2-asn` required together (or omitted). Uses test DBs in `test/`.
+- **Trusted headers**: `-trusted-header X-Real-IP` for proxy mode. When set without `-trusted-port-header`, client port shows "unknown".
+- **SIGHUP**: reloads GeoIP databases and restarts all servers without full stop.
+- **HTTP/3**: requires `-tls-bind`; reuses its port for UDP.
+- **Prometheus**: separate process/port via `-metrics-bind`. Metrics prefixed `whatismyip_*`.
+- **Port scan**: enabled by default; disable with `-disable-scan`.
+- **Embedded template**: `router/templates.go` has the default `home` template. `-template` overrides.
+- **Version**: injected at build via `-ldflags="-X 'github.com/dcarrillo/whatismyip/internal/core.Version=${VERSION}'"`.
+
+## Testing quirks
+
+- Integration tests need Docker (testcontainers-go) and will take longer. They run against a real containerized build.
+- Unit tests in `internal/setting/`, `internal/httputils/`, `internal/metrics/`, `internal/validator/uuid/`, `models/`, `router/`, and `service/` use test DBs from `test/`.
+- The router test reads `test/` resources by relative path — run from repo root.
+
+## Lint
+
+Uses `golangci-lint` v2 config (`.golangci.yaml`) with strict `revive` rules and `goimports` as formatter. One exception: `internal/metrics/` gets a pass on `var-naming` (package name conflicts with stdlib `metrics`). Also runs `shadow` and `gofmt -l -d`.
