> Reverse WHOIS for the .sk zone

Status: retired · 2018 · Data projects

**Problem.** After the company site was cloned for phishing, there was no way to find who registered what in .sk.

**Approach.** Wrote a custom SK-NIC EPP client (open-sourced as SK-NIC-EPP-Python), a collector and a 24/7 DNS/WHOIS monitor; 8 search vectors over 665,000 records.

**Result.** Retired with KlingonTech; the EPP library lives on GitHub.

**Stack.** Python, SK-NIC EPP, PostgreSQL
