Network Tools

WHOIS lookup, IP geolocation, DNS records, and SSL certificate checker

Four network tools in one place. Look up domain registration via RDAP, geolocate any IP address, query DNS records using Cloudflare's DNS-over-HTTPS, or check SSL certificate expiry via Certificate Transparency logs — all directly from your browser with no server-side processing.

Quick Guide
  • Enter a domain like example.com or paste a full URL
  • URLs like https://www.example.com/path are automatically normalized
  • Results include registrar, dates, nameservers, and status
  • Some registrant details may be redacted under GDPR/privacy policies
About IP Lookup
  • Enter any IPv4 or IPv6 address to retrieve geolocation and network info
  • Results include city, region, country, ISP/org, and ASN
  • Data is provided by ipapi.co — accurate to city level for most IPs
  • Private/reserved IPs (e.g. 192.168.x.x, 10.x.x.x) will return limited or no data
About DNS Records
  • Queries Cloudflare's DNS-over-HTTPS (DoH) resolver for accurate, live results
  • A / AAAA — IPv4 and IPv6 addresses for the domain
  • MX — Mail exchange servers and their priorities
  • TXT — Text records including SPF, DKIM, and DMARC policies
  • NS — Authoritative nameservers | CNAME — Canonical name alias | SOA — Start of Authority
About SSL Certificates
  • Looks up the most recent certificate from crt.sh Certificate Transparency logs
  • Results show issuer, validity dates, and days until expiry
  • Expiry is highlighted: red = expired, orange = <30 days, green = valid
  • CT log searches may take a few seconds — please be patient
