NepBox

Overview

NepBox is a free dynamic DNS (DDNS) management web app powered by the Cloudflare edge network. It solves a core problem: when your home broadband or server's public IP changes, how can you keep accessing your device via a fixed subdomain? ## Key Features - **One-click Google Sign-in**: No registration forms or passwords. Log in directly with your Google account; credentials are used solely for identity verification. - **Free Subdomains**: Receive a quota automatically upon login. Create up to 5 `*.nepbox.com` subdomains, and add or delete them anytime. - **A / AAAA Dual-stack Support**: Each subdomain can hold one A record and one AAAA record simultaneously, with IPv4 and IPv6 updated independently. - **One-line curl Updates**: An API lets you update DDNS from a router, NAS, or server with a single `curl` command. It auto-detects your public IP or accepts a manually specified address. Each domain has its own update token that can be reset anytime; only the token digest is stored. - **Instant Change Notifications**: Link Telegram to receive bot messages whenever a subdomain's IP address changes. - **Traceable Changes**: Every record change is logged, with the last 20 entries kept per domain. ## How It Works 1. Sign in with your Google account. The system creates your account and grants a subdomain quota automatically. 2. In the console, enter a name to create a subdomain, add an A or AAAA record, and copy your unique update token. 3. Configure the update URL in your router or a scheduled task like crontab. When your IP changes, it syncs to DNS automatically. ## Free Quotas & Limits NepBox is open for personal DDNS use with the following limits: - Subdomains: 5 - Record types: A / AAAA - Change logs: 20 per domain - Update rate: 20 per minute per IP - Address changes: 50 per day per domain ## Who Is It For? Individuals who need to pin down a dynamic IP—such as developers and hobbyists running a NAS, home server, Raspberry Pi, or needing remote access to a router.
