기능

도구

8 도구
alias_chain
Follow a CNAME chain
Use when a name is a CNAME and the person asks where it leads. Returns each hop with its target and TTL, and how it ends: addresses, none, a resolver failure, NXDOMAIN (dangling), a loop, or an inside name.

{'type': 'object', 'required': ['name'], 'properties': {'name': {'type': 'string', 'description': 'The name to follow, e.g. www.example.com. Also as "domain"; a URL is read as its host.'}}}
check_domain
Check a domain
Use when a domain or website is not working or not resolving (is it DNS?): one call. The first line says whether the name resolves; then the eleven-check audit of its zone, each row ok, warn, fail or skipped and why.

{'type': 'object', 'required': ['name'], 'properties': {'from': {'enum': ['north-america', 'europe'], 'type': 'string', 'description': 'Ask from the probe in this region'}, 'name': {'type': 'string', 'description': 'The domain to audit. Also as "domain"; a URL is read as its host.'}}}
dig
dig
Use for one exact question to one public resolver, not as the first call for a site that is not working. Returns records, flags, rcode, EDE and latency; DoH from the edge, or Do53 from a region's probe (from).

dnssec_chain
Walk the DNSSEC chain
Use when a name fails validation or the person asks whether its DNSSEC chain holds. Returns each signed zone cut from the root to the answer and the first link that breaks, or where it goes insecure.

path_receipt
Path receipt
Use when the person wants proof of what their resolver sends. First call: one dig to run. Second, with the nonce: what we saw (resolver address, UDP/TCP, DO, CD, EDNS size, cookie, ECS, case, arrivals) and the signed TXT.

registration
Registration status (RDAP)
Use when a domain has vanished from DNS and the person asks whether it expired or is on hold. Returns the registry's RDAP statuses and what each means for resolution, the dates and its nameservers; no contacts.

sweep_domain
Sweep a domain across its authoritative servers
Use after a zone change, when the person asks whether the authoritative servers agree. Returns each nameserver's answer to each name and type you list, the disagreements, lame or silent servers, and CAA and ACME readiness.

trace
Delegation walk
Use when the person wants to walk the delegation for a name, root to authoritative, like dig +trace. Returns each referral and glue, lame or unreachable servers, the final answer and a verdict.
