Normalize domains, URLs, IPs, and CIDRs, compare DNS snapshots locally, save evidence, and continue into DNS, WHOIS, TLS, PCAP, and firewall tools.
Network Investigation Lab normalizes a domain, IP address, CIDR, or HTTP URL and classifies special-use scope before you move into focused network tools. It does not silently scan a target or relay unrestricted requests through a server.
Paste bounded before-and-after DNS answer snapshots to identify added, removed, and TTL-only changes. Save normalized findings, notes, and tags as a local JSON evidence record, then continue into DNS, WHOIS, reputation, TLS, packet, subnet, redirect, and firewall analysis.
No. Target normalization and DNS snapshot comparison are local. Live DNS, WHOIS, reputation, redirect, or TLS activity occurs only after you explicitly open a focused lookup tool.
Enter an HTTP or HTTPS URL, a domain name, an IPv4 or IPv6 address, or an IPv4/IPv6 CIDR. The lab identifies private, loopback, link-local, multicast, and documentation ranges.
The parser accepts common dig answer lines, zone-style records, and normalized whitespace-separated records for A, AAAA, CNAME, MX, TXT, NS, SOA, CAA, SRV, PTR, DS, DNSKEY, and TLSA.
Instantly verify DNS records & email security settings: SPF, DKIM, DMARC, MX, A, AAAA, TXT, CNAME, NS, SOA. Free DNS diagnostics & troubleshooting.
Query domain registration information including registrar, nameservers, and expiration
Analyze SSL/TLS certificates, test protocol support, scan for vulnerabilities, and get security grades (A+ to F). Instant results with comprehensive security recommendations.
Analyze a .pcap or .pcapng packet capture in your browser. Get protocol breakdowns, top talkers, conversations, ports and TCP flags — no capture data is uploaded.
Build and test firewall rulesets with an interactive rule editor. Craft test packets to trace through rules, toggle stateless vs stateful inspection, view connection state tables, and analyze rule match statistics. Includes pre-built rulesets for web servers, DMZ, and corporate LAN.
