Add manual entries, comments, and external sources for a specific firewall job.
Firewall list publishing
Publish firewall IP lists your stack can trust.
Build allowlists, blocklists, and vendor ranges in one place. ListIPs validates every line, syncs approved sources, and publishes raw text endpoints that firewalls and scripts can consume without extra glue.
