Поиск DNS
Query DNS records for any domain using Cloudflare DNS-over-HTTPS.
DNS Record Types Explained
A · Maps domain to IPv4 address
AAAA · Maps domain to IPv6 address
CNAME · Alias pointing to another domain
MX · Mail exchange servers (with priority)
TXT · Arbitrary text (SPF, DKIM, domain verification)
NS · Nameservers authoritative for the domain
SOA · Start of authority, primary nameserver info
PTR · Reverse DNS, maps IP back to domain
How It Works
- Enter a domain: Type any domain name — including subdomains — into the input field.
- Select record types: Choose which DNS record types to query: A, AAAA, MX, CNAME, TXT, NS, SOA, or all of them.
- View results: Results are fetched from a public DNS-over-HTTPS provider and displayed with TTL values and record data.
- Diagnose issues: Compare results from different record types to identify misconfiguration, propagation delays, or missing records.
Why Use DNS Lookup?
DNS issues are among the most common causes of website downtime, email delivery failures, and domain migration problems. Being able to query DNS records directly from the browser — without using command-line tools like dig or nslookup — is valuable for developers, DevOps engineers, and sysadmins. This tool queries records via DNS-over-HTTPS for privacy and firewall bypass. Use it to verify MX records after changing email providers, confirm A/CNAME records after a DNS migration, check TXT records for SPF/DKIM email authentication, and diagnose propagation delays.
DNS Record Types
- A — IPv4 address for a domain
- AAAA — IPv6 address for a domain
- MX — mail server records for email routing
- CNAME — canonical name alias pointing to another domain
- TXT — text records for SPF, DKIM, domain verification
- NS — authoritative nameservers for the domain
