DNS Lookup Rapido
Cosa sono i DNS?
Il DNS (Domain Name System) è il sistema che traduce i nomi di dominio leggibili dall'uomo (come www.esempio.com) in indirizzi IP numerici che i computer usano per comunicare tra loro.
Senza DNS, dovresti ricordare l'indirizzo IP di ogni sito che vuoi visitare. I DNS funzionano come una rubrica telefonica di Internet.
Come funziona?
- Digiti un nome di dominio nel browser (es. www.esempio.com)
- Il resolver DNS interroga i server DNS per trovare l'indirizzo IP corrispondente
- Il browser si connette all'indirizzo IP e carica il sito web
Free DNS Tools Online — DNS Lookup, SPF/DKIM/DMARC Validation, and More
RecordDNS is a free online DNS tool that lets you perform all the DNS checks you need to manage and troubleshoot your domains. Whether you're a system administrator, webmaster, IT professional, or just curious, our DNS tools offer everything you need in one platform.
DNS Lookup: Complete DNS Record Search
Our free DNS lookup tool lets you query any domain and retrieve all major DNS record types: A records (IPv4), AAAA records (IPv6), CNAME records (aliases), MX records (mail exchange), TXT records, NS records (name servers), SOA records (start of authority), and DMARC records for email security. We also support ANY type queries for a complete analysis in one click.
Real-Time DNS Propagation Checker
Just changed your DNS records and want to know if they've propagated? Our DNS propagation checker queries DNS servers across different world regions (North America, Europe, Asia, Oceania) to show you the current propagation status. Each server is tested with a 5-second timeout, and results are displayed with intuitive color-coded indicators.
Email Authentication: SPF, DKIM and DMARC Validation
Email security is critical for deliverability. Our validators let you:
- SPF Validation: analyze your domain's SPF record, count lookups (max 10 per RFC 7208), identify mechanisms like include, ip4, ip6, a, mx, redirect, exists, and calculate a score from 0 to 100
- DKIM Validation: verify DKIM signatures with custom selectors, analyze the algorithm (RSA or Ed25519), key size, and record syntax
- DMARC Validation: check the policy (none/quarantine/reject), SPF and DKIM alignment, RUA/RUF reporting addresses, and calculate the overall configuration score
- Combined Email Auth Report: get a complete overview with all three protocols and a pie chart of the total score
Security Verification: SSL and DNSSEC
Keep your domain secure with our verification tools. The SSL certificate checker validates SSL/TLS certificates, checks for CAA records (Certificate Authority Authorization), and inspects certificates issued via Certificate Transparency logs. The DNSSEC validator checks for DS and DNSKEY records and confirms the response is authenticated with the AD (Authentic Data) flag.
Subdomain Enumerator and Domain Research
Discover all subdomains of a domain with our subdomain enumerator, which combines data from Certificate Transparency (crt.sh) with a wordlist of over 200 common subdomains tested via direct DNS queries. Get information about IP addresses, CNAME records, and activity status for each discovered subdomain.
WHOIS Lookup and Reverse DNS
The WHOIS lookup tool retrieves domain registration information from multiple sources (direct RDAP, registry RDAP, whois.com) with automatic fallback. The reverse DNS (PTR lookup) tool lets you find the hostname associated with an IP address, essential for email deliverability and network troubleshooting.
Security Headers and DNS-over-HTTPS
The HTTP Security Headers checker analyzes your website's security headers: HSTS, Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, and many more, calculating an overall score. The DNS-over-HTTPS (DoH) checker verifies whether the domain supports encrypted DNS queries via HTTPS (SVCB) records.
All our tools are completely free, require no registration, and run directly in your browser using public Google DNS and Cloudflare DNS APIs. You can export results in TXT, JSON, or CSV format and copy them with one click. Available in Italian and English.
