About ListIPs
A small, focused publisher for firewall IP lists.
ListIPs gives system administrators and DevOps teams one place to validate, synchronize, and publish IP and CIDR lists without building a custom delivery service.
Purpose
Why ListIPs exists
Firewall lists often begin as text files copied between machines, scripts, and control panels. That works until validation, source updates, access control, and stable delivery become separate maintenance problems.
ListIPs keeps that scope deliberately narrow: accept line-oriented IP data, validate it, combine approved sources, and serve a clean raw artifact over HTTPS.
Architecture
Cloudflare-native delivery
Static Astro frontend
Public information and the account interface are rendered as lightweight pages.
Worker API
Authentication, validation, list changes, raw delivery, and rate limiting run at the edge.
D1 and R2 storage
D1 stores account and list metadata; R2 stores compiled raw list artifacts.
Queued synchronization
External source updates run in background jobs and publish only validated output.
Project
Open source and inspectable
The source code, deployment configuration, tests, and architecture notes are available in the public repository. ListIPs is built by ViWeb Technology.
