Changelog

All notable changes to NextDNS Medic are documented here.

[2.3.1] — 2026-03-26

Added

• Pi-hole blocklist attribution — for Pi-hole v6 users, blocked domains now show which gravity list flagged them (e.g. "Steven Black Unified", "HaGeZi — Multi", "OISD Full"). Uses the Pi-hole /api/search/{domain} gravity endpoint. Includes a pretty-name map for 30+ popular lists:
  • HaGeZi (Multi, Pro, Pro++, Ultimate, Threat Intelligence)
  • Steven Black Unified
  • OISD (Full, Basic, Small)
  • AdGuard DNS filter
  • EasyList / EasyPrivacy
  • Disconnect.me (Ads, Tracking, Malware)
  • Energized (Basic, BLU, Ultimate)
  • URLhaus Malware
  • WindowsSpyBlocker
  • Unknown lists fall back to their hostname

Developer

• npm run pihole:start now exposes port 53 (UDP + TCP) for local DNS testing
• npm run dns:pihole — sets system DNS to 127.0.0.1 (Pi-hole) on the active interface
• npm run dns:restore — restores system DNS to automatic (DHCP)

  • New categories: CAPTCHA (24), video players (33), maps (15), support chat (37), image CDNs (9), error monitoring (28)
• Functional impact badges — every blocked domain shows a color-coded badge describing the specific consequence of blocking it:
  • 🔴 Red — login / forms (auth, payments, CAPTCHA)
  • 🔵 Blue — media / maps / assets (video, maps, image CDNs, CDN)
  • 🟢 Green — chat / notifications (support chat, real-time)
