Resolve A/AAAA/MX/TXT/NS/CNAME (Node dns; answers from the Forge host resolver).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
## What this skill does
Resolve A/AAAA/MX/TXT/NS/CNAME (Node dns; answers from the Forge host resolver)
中文：解析 A/AAAA/MX/TXT/NS/CNAME 等记录（Node dns，结果随 Forge 出口解析器）
## When to use
- Human or agent needs **DNS Lookup** (`net/dns-lookup`).
- Tier: `core` · side-effect: `pure` · meter: `forge.net.dns_lookup`.
## How to invoke
```http
POST /api/v1/tools/invoke/net/dns-lookup
Content-Type: application/json
{"input":{}}
```
MCP name: `net__dns-lookup`
## Engine
- **node:dns** runtime
- Upstream: https://nodejs.org/api/dns.html
## Composition (next)
Chain these after a successful run when the job continues:
- (none seeded yet)
## Limits
- Prefer pure/deterministic path; do not invent model calls.
- Respect input schema validation errors from invoke.Read the whole file at its exact version.
How to install
mdr add nebutra/nebutra-sailor/dns-lookup@sha256:4fecbd6baa7c415eThe line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
