About This Tool
The DNS Lookup tool queries authoritative Domain Name System (DNS) records for any domain name or hostname, displaying active IP mappings, mail exchangers, and verification tokens.
### How DNS Resolution Works When you query a domain, the tool resolves records using Google Public DNS over HTTPS (DoH) API endpoints: - **A Records**: Maps human-readable domain names to 32-bit IPv4 addresses (e.g., `192.0.2.1`). - **AAAA Records**: Maps domains to 128-bit IPv6 network addresses. - **MX Records**: Directs incoming email traffic to designated mail exchange servers with priority weights. - **TXT Records**: Hosts machine-readable metadata including SPF (Sender Policy Framework), DKIM keys, and SSL ownership verification hashes. - **CNAME Records**: Canonical alias mapping one domain name to another fully qualified domain. - **NS Records**: Identifies the authoritative nameservers responsible for the domain zone.
### Worked Example Querying the domain `example.com`: - **A Record**: `93.184.216.34` (TTL 3600) - **AAAA Record**: `2606:2800:220:1:248:1893:25c8:1946` - **NS Records**: `a.iana-servers.net`, `b.iana-servers.net` - **TXT Record**: `v=spf1 -all`
### Processing & Network Transparency Resolving public DNS records requires network transmission. Your query target is sent via secure HTTPS to public DNS resolver endpoints (such as Google Public DNS) to fetch the latest zone data. No personal browsing histories or private internal hostnames are logged on Ubify servers.
How to Use
- 1
Enter the domain name (e.g., example.com) into the hostname field.
- 2
Click Scan DNS to initiate the secure DNS over HTTPS query.
- 3
Inspect the returned record array categorizing A, AAAA, MX, TXT, and NS entries.
- 4
Copy specific IP addresses, mail exchange priorities, or verification strings.
Frequently Asked Questions
Why might recent DNS changes not show up immediately?
DNS records are cached globally based on their Time-To-Live (TTL) values. If you recently updated your nameserver or A record, older values may remain cached until the TTL expires.
Does this tool support reverse DNS (PTR) lookups?
The primary query resolves forward zone records (ANY query) for a given domain name rather than pointer records from IP addresses.
Is my domain query private?
Queries are routed securely via encrypted HTTPS to standard public DoH endpoints. Ubify does not store or analyze your queried hostnames.
