DNS Lookup: Check DNS Records Online in Your Browser
Use DNS Lookup to query a hostname or IP address for A, AAAA, CNAME, MX, NS, TXT, SOA, CAA, SRV, PTR, DS, DNSKEY records, or all common types at once. Select Cloudflare or Google DNS-over-HTTPS as the resolver. Results show each record's type and TTL, along with the DNSSEC AD flag, so you can inspect the response in your browser.
DNS Lookup is a browser-based DNS lookup tool for checking records associated with a hostname or IP address. It supports A, AAAA, CNAME, MX, NS, TXT, SOA, CAA, SRV, PTR, DS, and DNSKEY queries, as well as an option to query all common types at once. Use it to inspect DNS responses without installing a command-line client on the machine you are using.
Choose the record type you need and select Cloudflare or Google DNS-over-HTTPS as the resolver. The results include the record type and TTL, along with the DNSSEC AD flag. These details help you see what records the resolver returned and the TTL associated with each result; the tool queries DNS rather than converting data between formats.
DNS records serve different purposes: for example, A and AAAA records return address information, MX records are used for mail routing, and TXT records contain text data associated with a domain. Looking up specific types can help developers and DevOps engineers investigate configuration or troubleshoot DNS-related questions. Querying all common types is useful when you want a broader view of the available records.
The tool runs in your browser, but a lookup requires a network connection. The hostname or IP address you enter is sent to the selected public DNS-over-HTTPS resolver so it can answer the query; My-DevTools itself stores nothing. DNS Lookup does not work offline because it must reach a resolver.
DNS Lookup can help developers, DevOps engineers, and anyone who needs to inspect DNS records from the browser. It is useful for quick checks on a workstation or another machine where installing a command-line client is not convenient.
Step 1: Enter a hostname or IP address to look up. The query uses the value you provide to request DNS records.
Step 2: Choose a record type, such as A, MX, TXT, or DNSKEY, or select the option to query all common types at once.
Step 3: Select Cloudflare or Google DNS-over-HTTPS as the resolver for your lookup.
Step 4: Run the query and review the returned records. Each result includes its record type and TTL, plus the DNSSEC AD flag.
Step 5: Copy the result when you need to use or share the lookup output elsewhere.
Use case: Check a hostname's A or AAAA records while investigating whether it has IPv4 or IPv6 DNS entries.
Use case: Inspect MX records when troubleshooting email routing or reviewing a domain's mail configuration.
Use case: Look up TXT records when checking DNS-based verification or other TXT-based domain settings.
Use case: Review CNAME or NS records to understand the DNS records returned for a hostname.
Use case: Query SOA, DS, DNSKEY, or the DNSSEC AD flag when examining DNS and DNSSEC information.
Use case: Run a lookup from a machine without installing a command-line DNS client, using a browser and a choice of Cloudflare or Google DNS-over-HTTPS.
