NSLOOKUP
Kiểm tra bản ghi DNS mà không có tiếng ồn.
Query DNS records, trace authoritative delegation, or reverse lookup IPv4 and IPv6 addresses.Queries run on the Arcvenza API server without application caching. Authoritative mode traces DNS delegation; recursive mode may return cached records. IP addresses automatically use PTR.Read the result in context
Query a public domain or IP address and choose the record type that answers your question. Use authoritative mode to trace delegation, or recursive mode to inspect the selected resolver's response. Recursive answers may be cached. An IP-address query uses PTR.
Queries run on Arcvenza's server. Keep the displayed test node and timestamp with the result; the response is not a measurement of your own device's resolver. Compare the status, answering server, record type, TTL, and value before making a DNS change.
Copy the summary or records, or export the available JSON or CSV result. Check the exported rows against the visible answer. Do not submit confidential internal names, credentials, or personal data. For a missing name, read the NXDOMAIN guide for a local timeout, follow the resolver troubleshooting guide.
