IP/ASN lookup that's instant, but what problem does it solve better than ipify or ip-api?

Strengths
  • Local .mmdb parsing means zero external API calls and deterministic latency
  • Clean, functional UI shows all relevant details: IP, ASN, country, ISP in one view
Weaknesses
  • Solves a non-problem: ipify, ip-api, and curl ifconfig.me already handle this freely
  • No differentiation—speed advantage of local lookup is marginal for a tool called once per session
Target Audience

Network engineers, DevOps, developers debugging connectivity issues
