Enter a domain name to view all of its common dns records (A, AAAA, CNAME, MX, TXT, SRV, DMARC).
Enter an ip address to perform a reverse dns lookup (PTR). Supports IPv4, IPv6, and FCrDNS.
Query a specific nameserver by adding @nameserver (ex. www.example.com@ns1.misk.com).
Lookups are not cached, providing real time results (dns record caching).
Enter a domain name to view its whois record (ownership, registrar, expiration, etc.).
Enter an ip address to view its internet service provider.
Enter a domain name OR ip address to view the path a request takes to reach an ip from our server.
This tool can help you troubleshoot routing issues and find service provider information.
Perform a dns lookup to query a domain's dns records (e.g., misk.com) and view its A, AAAA, CNAME, MX, TXT, SRV, and DMARC records. Results are obtained in real time directly from the domain's authoritative nameservers, bypassing dns record caching, so you can check dns propagation and verify recent changes have taken effect. An online alternative to nslookup and dig.
Reverse DNS Lookup
Enter an IP address (e.g., 199.47.128.30) to perform a reverse dns lookup (rDNS). Queries the PTR records for an IP to find its associated hostname. Both IPv4 and IPv6 are supported. Performs an automatic forward confirmed reverse dns lookup (FCrDNS) to verify that the PTR hostname resolves back to the original IP. Important for email deliverability since many mail servers reject messages from IPs that fail FCrDNS. Learn more about reverse dns.
Query Specific Nameserver
Add @nameserver after any domain to query a specific dns server. Results include NS records for the domain.
Authoritative nameservers (e.g., misk.com@ns1.misk.com) - verify a nameserver's records directly
Dns delegation (e.g., misk.com@a.root-servers.net) - trace NS referrals from root to authoritative, with lame delegation detection
