DNS Lookup
Query A, AAAA, MX, TXT, CNAME, NS, and SOA records from a neutral server, or reverse-lookup an IP's hostname.
Looks up the PTR record for an IP address. Not every IP has one.
Enter an IP address to find its hostname
The PTR record, if one is set for that address, appears here.
DNS Lookup queries a domain's DNS records directly and returns what the domain name system currently resolves for that name: the IP address it points to (A/AAAA), where its mail is routed (MX), and any policy or verification data stored in TXT records.
Each record type serves a different purpose. A and AAAA records determine where a website's traffic is routed. MX records determine where email is delivered. CNAME records point one hostname to another rather than to an IP address directly. NS records declare which servers are authoritative for the domain. TXT records carry free-form data used for SPF, DKIM, DMARC, and third-party domain ownership verification.
Results are returned by a neutral, server-side resolver rather than a local device cache, so they reflect what the broader internet currently sees. This is particularly useful immediately after a DNS change, when a local machine may still return a stale, cached answer.
