📖 How to Use DNS Records Lookup (DoH 1.1.1.1)? (Step-by-Step Guide)

Step 1

Enter any domain name or subdomain (e.g. `denizlihub.com` or `google.com`) into the lookup field.

Step 2

Select the DNS record types to query (`A`, `AAAA`, `MX`, `TXT`, `NS`, `CNAME`, `SOA`) or query all at once.

Step 3

Click 'Lookup DNS' to fetch live records directly via RFC 8484 DNS-over-HTTPS (DoH) resolvers.

Step 4

Inspect resolved IP addresses, mail server priorities, SPF/DMARC TXT policies, and TTL cache timers.

⚙️ IETF RFC 1035 & RFC 8484 DNS-over-HTTPS (DoH) Zone Diagnostics

The Domain Name System (RFC 1035) is the phonebook of the internet—translating human-readable hostnames into IPv4/IPv6 routing addresses, mail exchange endpoints, and cryptographic domain ownership policies.

DH Tools queries global anycast resolvers over encrypted DNS-over-HTTPS (RFC 8484) to display live `A`, `AAAA`, `MX`, `TXT`, `NS`, `CNAME`, and `SOA` resource records along with exact TTL expiration timers.

🎯 Real-World Industry Use Cases

✓ Website Migration & Propagation Checks Verify that updated `A`, `AAAA`, and `CNAME` records resolve to your new hosting IP or CDN.

✓ Email Deliverability & Anti-Spam Auditing Inspect `MX` priorities and verify `v=spf1` TXT records for Google Workspace or Microsoft 365.

✓ Domain Ownership Verification Confirm Google Search Console, Cloudflare, or SSL ACME challenge `TXT` records are live.

✓ Nameserver & SOA Authority Inspection Check authoritative `NS` delegation and primary `SOA` serial numbers.

❓ Frequently Asked Questions

An `A` record maps a domain to an IPv4 address (`AAAA` maps to IPv6). A `CNAME` aliases one subdomain to another domain. `MX` directs email to mail servers with priority numbers, and `TXT` stores text verification records like SPF, DKIM, DMARC, and Google Site Verification.

TTL is the number of seconds (e.g. `300` = 5 minutes, `3600` = 1 hour) that recursive DNS resolvers are allowed to cache the record before asking the authoritative nameserver again.

If your previous record had a high TTL (such as `86400` seconds = 24 hours), ISP resolvers may continue serving the cached value until that TTL expires.

We query global Cloudflare (`1.1.1.1`) and Google (`8.8.8.8`) recursive resolvers using encrypted IETF RFC 8484 DNS-over-HTTPS (DoH) JSON APIs.
