What is a DNS lookup?
Resolve domains and inspect every common record type at once.
About DNS lookups
DNS (Domain Name System) is the internet's address book. When you type example.com into a browser, DNS translates that human-readable name into the IP address the computer actually needs to connect. This tool queries every common record type — A, AAAA, MX, TXT, NS, CNAME, SOA — at the same time and groups the answers for easy scanning. All queries go over DNS-over-HTTPS (Google + Cloudflare) so your lookups are private.
Returns every record type (A, AAAA, MX, TXT, NS, CNAME, SOA).
How DNS lookups work
DNS (Domain Name System) is the internet's address book. When you type example.com into a browser, DNS translates that human-readable name into the IP address the computer actually needs to connect. This page queries every common record type — A, AAAA, MX, TXT, NS, CNAME, SOA — in parallel and groups the answers for easy scanning. Queries are sent over DNS-over-HTTPS (Google + Cloudflare) so your lookups are private.
Record types
- A — maps a name to an IPv4 address.
- AAAA — maps a name to an IPv6 address.
- MX — lists the mail servers that accept email for the domain.
- TXT — arbitrary text, commonly used for domain verification (Google, Microsoft) and email policy (SPF, DKIM, DMARC).
- NS — lists the authoritative name servers for the domain.
- CNAME — creates an alias from one name to another.
- SOA — administrative information about the zone (serial, refresh, retry, expire, minimum TTL).
Frequently asked questions
What is a DNS lookup?
A DNS lookup is a query sent to a DNS resolver asking for the records associated with a domain name. The most common query is for the A record (the IPv4 address), but DNS also stores AAAA (IPv6), MX (mail servers), TXT (verification and policy), NS (name servers), CNAME (alias), and SOA (zone authority) records.
What are the different DNS record types?
A maps a name to an IPv4 address. AAAA maps to IPv6. MX lists mail servers for the domain. TXT stores arbitrary text, commonly used for domain verification (Google, Microsoft, Facebook) and email policies like SPF/DKIM/DMARC. NS lists the authoritative name servers for the domain. CNAME creates an alias from one name to another. SOA holds administrative information about the zone.
Which record type should I look up?
You don't have to choose — this tool queries every common record type at once. For "where does this domain point," look at A and AAAA. For "where does its email go," look at MX. For "who runs this domain's DNS," look at NS. For "is this domain verified by Google/Microsoft/etc.," look at TXT. For "is this subdomain an alias of something else," look at CNAME.
What is DNS-over-HTTPS?
DNS-over-HTTPS (DoH) encrypts DNS queries so that no one on the path between you and the resolver can see what domains you are looking up. Traditional DNS sends queries in cleartext, which means your ISP, coffee-shop Wi-Fi, or anyone else on the network can log every site you visit. This tool uses DoH (via Google and Cloudflare) so your lookups are private.
Why are my DNS records different from what I configured?
DNS changes take time to propagate. Most resolvers respect the TTL (time to live) on each record and refresh from the authoritative server when it expires. Typical propagation is minutes to a few hours, but in some cases it can take up to 48 hours. If you just changed a record, wait and look up again later.
