Enter a domain and click Lookup to query DNS records.
Enter one domain per line. All domains will be queried for the same record type.
Quick reference for common DNS record types and their uses.
| Type | Full Name | Purpose | Example Value |
|---|---|---|---|
| A | Address | Maps a domain to an IPv4 address | 93.184.216.34 |
| AAAA | IPv6 Address | Maps a domain to an IPv6 address | 2606:2800:220:1:248:1893:25c8:1946 |
| CNAME | Canonical Name | Alias pointing to another domain name | www.example.com ? example.com |
| MX | Mail Exchange | Specifies mail servers for the domain | 10 mail.example.com |
| TXT | Text | Arbitrary text; used for SPF, DKIM, DMARC, domain verification | v=spf1 include:_spf.google.com ~all |
| NS | Nameserver | Authoritative nameservers for the domain | ns1.cloudflare.com |
| TTL | Time To Live | Cache duration in seconds (not a record type) | 3600 = 1 hour |
Common TXT Record Prefixes
| Prefix | Protocol | Purpose |
|---|---|---|
v=spf1 | SPF | Authorised senders for email (reduces spam) |
v=DKIM1 | DKIM | Email signing key for origin verification |
v=DMARC1 | DMARC | Email policy: reject/quarantine/monitor unverified mail |
google-site-verification= | Proves domain ownership to Google Search Console | |
MS=ms | Microsoft | Proves domain ownership for Microsoft 365 |
DoH Resolver Endpoints
| Resolver | Endpoint | Privacy |
|---|---|---|
| Cloudflare 1.1.1.1 | https://cloudflare-dns.com/dns-query | Logs purged within 24 h |
| Google 8.8.8.8 | https://dns.google/resolve | Logs retained per Google policy |
How to Use the DNS over HTTPS Lookup Tool
To use the DNS over HTTPS Lookup Tool, follow these steps:
1. Enter a domain name in the input field. Do not include http:// or a trailing slash.
2. Select the record type you want to look up (A, AAAA, MX, TXT, CNAME, or NS).
3. Choose a resolver (Cloudflare 1.1.1.1, Google 8.8.8.8, or both).
4. Click 'Lookup' to see the DNS records in a table, including the TTL and which resolver returned the data.
When to Use the Tool in Real Workflows
The DNS over HTTPS Lookup Tool is ideal for anyone who needs to verify DNS records for troubleshooting, security, or compliance purposes. It's particularly useful for developers, system administrators, and IT professionals who need to ensure that their DNS configurations are correct and up-to-date.
How It Works
The tool uses DNS over HTTPS (DoH) to query DNS records. When you click 'Lookup', your browser makes a direct fetch() call to the selected resolver's HTTPS endpoint. The resolver returns the DNS records in JSON format, which the tool then displays in a user-friendly table. This process ensures that your queries are encrypted and private, preventing your ISP or network observer from seeing which domains you are looking up.
Tips, Edge Cases, and Limitations
1. Batch Mode: You can enter multiple domains (one per line) to look them up in one click. This is useful for bulk operations.
2. Download Results: You can download the results as a CSV file for further analysis.
3. Resolver Comparison: Comparing results from different resolvers (Cloudflare and Google) can help identify any discrepancies in DNS configurations.
4. Record Types: The tool supports various record types including A, AAAA, MX, TXT, CNAME, and NS. Each type serves a specific purpose in DNS configuration.
5. Privacy: By using DoH, your queries are encrypted and private, ensuring your data remains secure.
