🔍 DNS Lookup
A DNS lookup turns a domain name into the records the internet uses to route mail, find web servers, or verify ownership. This tool queries Cloudflare's public DNS-over-HTTPS resolver, the same one millions of devices use. Type a domain, pick which records you want, get them.
Examples
google.com (A record)142.250.190.46, 142.250.191.46, ...gmail.com (MX record)gmail-smtp-in.l.google.com priority 5, ...yoursite.com (TXT)google-site-verification=..., v=spf1 ...Frequently asked questions
What is each record type for?
A = IPv4 address. AAAA = IPv6. MX = mail server. TXT = verification + SPF + DKIM. NS = which nameservers run the domain. CNAME = alias to another domain. SOA = authoritative metadata.
Why are there multiple A records?
Big sites load-balance across many servers. The resolver returns all of them and your browser picks one. Order may rotate (round-robin DNS).
Cloudflare vs Google DNS?
Both free, fast, public. Cloudflare (1.1.1.1) is privacy-focused. Google (8.8.8.8) is the older default. We use Cloudflare for this lookup.
