The old Toolbox Dig URL became a common bookmark because it provided a quick web version of a DNS dig lookup. This page keeps that job clear: enter a name, pick a record type, and inspect the DNS answer.
Equivalent lookup tasks
| Task | Record type | Why it matters |
|---|---|---|
| Website IPv4 | A | Shows the IPv4 address returned for a domain. |
| Website IPv6 | AAAA | Shows the IPv6 address, which can explain failures on IPv6-capable networks. |
| Email routing | MX | Shows where inbound email should be delivered. |
| Verification and policy | TXT | Used by SPF, DKIM, DMARC, ownership checks, and certificate challenges. |
| Delegation | NS and SOA | Shows which name servers and zone metadata are visible publicly. |
Useful differences to remember
An online dig tool normally queries from the server where the tool runs. Your laptop, your ISP resolver, and an online tool can sometimes see different cached answers. That difference is not a bug; it is often the clue that a DNS change is still propagating or that one resolver has stale cache.
Suggested troubleshooting flow
- Run the record in the browser tool.
- Compare the result against your DNS provider dashboard.
- If the value differs, query multiple public resolvers.
- If delegation looks wrong, check NS and SOA before changing individual records.
