Related tools

Online tool for advanced DNS lookups (nslookup / DIG-style). By default, it performs recursive queries against authoritative name servers - but custom DNS resolvers are supported too. Includes secondary records for a complete overview and provides a full technical log for debugging and insight.

WHOIS / RDAP lookup

Perform WHOIS and/or RDAP lookups on domains, IP addresses, and ASNs. Will output all available technical info, contact info, etc.

Perform rDNS lookups on IPv4 or IPv6 addresses. Check PTR records to see the hostname behind any IP.

CIDR calculator

IP to CIDR calculation tool with subnet info. The reverse, CIDR ranges to IP addresses, is also possible. Last but not least, it includes a tool for refactoring groups of IPs, domain names, and/or other CIDR ranges.

What is my IPv4 and IPv6?

Check your IPv4 and IPv6 address and analyze your network setup. Includes ISP/ASN lookup, DNS resolver detection, browser and device information, and connectivity diagnostics in a shareable report.

GeoIP lookup tool. Supports lookup of ip's in bulk - and lookups based on domainnames. Includes ASN/ISP data. Based upon the MaxMind database.

World map, day/night + local time

Beautiful day/night map of the world, with markup of all major cities including local date and time.

Ping / traceroute

Ping tool for testing connectivity to a host, measuring response times, jitter, and packet loss. Global ping works like regular ping — but from multiple sources worldwide, simultaneously. Traceroute maps the full path data takes, showing each hop’s response time, ASN, and geo-info to diagnose network issues.
