DNS Lookup

查询 DNS 记录。

Enter a value and run.

This tool is not browser-only: your input is sent through toco.tools servers. Private/local destinations are blocked. Results are not stored.

关于DNS Lookup

DNS lookup shows which addresses and records a hostname resolves to—useful for mail and migration checks. toco.tools performs resolution on the server because browsers cannot issue arbitrary DNS queries. Results reflect the resolver answer at query time.

使用方法

  1. Enter a hostname
  2. Run the lookup
  3. Review each record type

常见问题

Can this run fully in the browser?

No. DNS resolution runs on the server.

Which records are shown?

A, AAAA, MX, TXT, CNAME, and NS.
