DNS Lookup

How to Use the DNS Lookup Tool

Enter any domain name (e.g. example.com) or IP address (for PTR lookups), choose a record type, select a DNS server, and click Lookup. Queries run entirely in your browser using DNS-over-HTTPS — no data is sent to EpicTools servers.

Record Types Explained

• A — Maps a domain to one or more IPv4 addresses. Multiple A records indicate round-robin DNS, load balancing, or CDN usage.
• AAAA — Same as A but for IPv6 addresses. The presence of AAAA records means the domain supports IPv6 connectivity.
• CNAME — An alias that points one domain name to another. Queries continue resolving the target domain. CNAME records cannot coexist with other record types at the same name.
• MX — Identifies mail servers responsible for accepting email for the domain. Lower priority numbers are more preferred. Sorted by priority automatically.
• NS — Lists the authoritative nameservers for the domain. At least two NS records are recommended for redundancy.
• TXT — Arbitrary text records. Used for SPF email policy, domain ownership verification (Google, Microsoft, etc.), DKIM public keys, and more.
• SOA — Start of Authority. Contains zone metadata including the primary nameserver, admin contact, serial number, and timing parameters for zone transfers.
• PTR — Reverse DNS. Maps an IP address back to a hostname. Used for email reputation and network diagnostics. Enter an IP address in the query field.
• SRV — Service records that define the hostname and port for specific services (e.g. SIP, XMPP). Priority and weight control load balancing.
• CAA — Certification Authority Authorization. Restricts which certificate authorities may issue TLS certificates for the domain. Improves certificate security.
• ALL — Queries A, AAAA, CNAME, MX, NS, TXT, SOA, CAA, and SRV in parallel and shows all results with records found. PTR is excluded since it requires an IP address input.

DNS Servers

• Cloudflare (1.1.1.1) — Fast public resolver with strong privacy focus. Generally reflects current DNS state quickly.
• Google (dns.google) — Google's public DNS. Useful for cross-checking results against Cloudflare.
• Quad9 (dns.quad9.net) — Privacy-focused resolver that also blocks known malicious domains.
• NextDNS — Flexible DNS resolver with filtering options. Anonymous queries use their base endpoint.

If results differ between providers, it usually means DNS propagation is still in progress or the providers have cached different values. TTL values shown indicate how long the record is cached.
