A fast and multi-purpose DNS toolkit from ProjectDiscovery for running DNS probes, resolving records and filtering DNS responses.
InfoSniper is a free IP address lookup service that locates an IP on an interactive map with city, region, country, ISP, ASN, timezone and coordinates, supporting IPv4 and IPv6. It also offers XML and JSON REST APIs requiring an API key for IP geolocation data.
DNSViz is a tool for visualizing the status of a DNS zone. It was designed to help understand and troubleshoot deployment of the DNS Security Extensions, providing a visual analysis of the DNSSEC authentication chain and resolution path and listing configuration errors it detects.
digga is a free domain and infrastructure research tool that looks up DNS records, RDAP and WHOIS data, subdomains, IP details and email authentication in one report. It supports many DNS record types and passive subdomain enumeration. The project is open source under AGPL 3.0 with no accounts or paywalls.
SSL Server Test is a free online service from Qualys SSL Labs that performs a deep analysis of the configuration of any SSL web server on the public Internet. The site states that submitted information is used only to provide the service.
DNSai is a collection of DNS and email security tools on one page. It covers DNS record lookups, WHOIS, blacklist checks, SPF, DKIM and DMARC builders and validators, email header analysis and bulk domain scanning. The tools return plain-English AI summaries, and each is available through an API and MCP connectors.
Web Check is described as an all-in-one OSINT and security tool for revealing the inner workings of a website. It reports on items such as IP information, SSL certificates, DNS records, cookies, crawl rules and response headers.
