NetGuard Egress IP Sentinel

Alert when your egress IP changes and avoid AI service bans

Problem

Users of Claude Code and similar AI services get banned when their egress IP silently jumps to another region, gets flagged as a datacenter or proxy, or IPv6 bypasses the tunnel—only discovering the network issue after the fact. Web-based IP checkers show only the current moment, with no continuous monitoring, timeline, or comprehensive check for DNS leaks and split-routing inconsistencies.

Solution

A menu bar macOS network sentinel that periodically checks egress IP and region, notifies and logs changes to a timeline, and offers a one-click network health check covering local machine, DNS, egress, IP reputation, and target sites—surfacing IPv6 bypass, DNS leaks, and timezone-egress mismatches with fix suggestions.

Users

Developers using overseas AI services like Claude Code and OpenAI, cross-border e-commerce sellers, remote workers, and anyone sensitive to network egress.

MVP

Periodic egress IP and GeoIP region change detection with notifications; timeline of every change; one-click check for DNS leaks, IPv6 bypass, and timezone consistency; menu bar widget showing current status; custom check targets.

Revenue

One-time desktop app purchase ($12.99–$19.99); premium tier adds multi-location history comparison and alert integrations (Slack/Webhook).

Why now

AI coding tools are ubiquitous and account risk control is increasingly sensitive to egress IP; existing tools either check IP once or target enterprise network monitoring, leaving a gap for a lightweight personal sentinel.
