Updating the GEO databases

GEOIP and GEOSITE rules rely on local databases to classify IPs and domains. Stale databases cause misrouting — refresh them periodically.

What GEO data is

The GeoIP database maps IP ranges to countries (what a rule like GEOIP,US,DIRECT relies on); the GeoSite database maintains categorized domain lists (e.g. the geosite:category-ads-all ad-domain set). Sites and IP allocations change constantly, so the databases must keep up.

Update steps

  1. Open the Settings page and find the “Clash Core” area.
  2. Click the “Update GeoData” button.
  3. Wait for the download; the core loads the new data automatically.
  4. If the download crawls, enable the proxy first and retry.
