DNS 조회
도메인의 일반적인 DNS 레코드 유형을 쿼리합니다. DNS 변경 사항이 전파되는 데 시간이 걸릴 수 있으며, 캐시된 리졸버는 업데이트 중에 다른 결과를 표시할 수 있습니다.
이 도구가 확인하는 항목
지원되는 레코드는 A, AAAA, CNAME, MX, TXT, NS입니다. 포트 스캔, 라우트 추적 또는 대량 조회는 수행하지 않습니다.

DNS tells the rest of the web where a domain should point. Use this tool when you want to validate domain setup, troubleshoot reachability, or spot unexpected hosting and mail routing changes.
The tool is read-only: it checks a single domain at a time and returns only the selected record type.
Best use cases
- Checking whether a domain points to the expected web server.
- Finding potential typos in email infrastructure by reading MX priorities.
- Verifying whether a CDN front-end and backend host are both represented.
How to use DNS lookup
Enter a valid domain and choose one record type to fetch the latest authoritative answer path available to resolvers.
A practical workflow
- Start with A and AAAA. If both differ, confirm whether a service intentionally supports IPv4-only or IPv6-only paths.
- Use CNAME only when you are debugging canonical host mapping in subdomains.
- Use MX when you verify where email for the domain is delivered.
- Use TXT for SPF, DKIM, and domain verification hints.
- Use NS to confirm the authoritative name servers shown on most control panels.

Common checks before changing DNS
-
Why do answers differ between networks?
Some resolvers use different cache states, so propagation time and existing cache TTL can create short windows with old values.
-
Can this tool replace full DNS diagnostics?
No. For full diagnostics use packet-level tools and TTL analysis, but this lookup is enough for most configuration verification.
