iKuai DDNS: Bind LAN IPv6 to Domain

# iKuai DDNS: Bind LAN IPv6 to Domain ## 📋 Content Overview This video provides a comprehensive tutorial on configuring IPv6 Dynamic DNS (DDNS) functionality in iKuai OS router system, enabling LAN devices to be accessed via fixed domain names even when IPv6 addresses change dynamically. This is a practical beginner's guide for iKuai OS users. --- ## 🔑 Key Highlights **iKuai's Unique DDNS Implementation** Unlike traditional DDNS solutions (such as Synology's built-in DDNS or ddns-go), iKuai OS adopts a **router-level unified management approach**: - **Traditional approach**: Requires installing and configuring ddns-go or similar tools on each device (NAS, PC, etc.) - **iKuai approach**: Configure once on the router, all connected devices gain DDNS service without installing any software --- ## 💡 Technical Advantages 1. **Centralized Management**: One-time configuration, benefits all devices 2. **Zero Client Software**: No need to install DDNS programs on individual devices 3. **Native IPv6 Support**: Fully leverages IPv6's unique public address per device 4. **Versatile Applications**: Ideal for remote streaming (Sunshine + Moonlight), remote NAS access, and more --- ## 📝 Prerequisites ### 1. Obtain DNSPod TOKEN Apply for an API TOKEN from DNSPod platform (includes TOKEN ID and TOKEN secret) ### 2. Prepare Domain Name - Example structure: `dpit-v2-v6-ikuai-nas.lab00.com` - Recommended to include "v6" identifier for distinguishing IPv4/IPv6 dual-stack - Actual usage can be simplified ### 3. Manually Add DNS Record Add an **AAAA record** in DNSPod (IPv6 corresponds to 4 A's): - Host record: Enter domain prefix - Record value: Enter any IPv6 address (will auto-update later) - **Important**: iKuai can only update existing records, not create new ones ### 4. Obtain Device DUID In iKuai OS: - Navigate to: `Network Settings` → `IPv6` → `DHCPv6 Clients` - Locate target device and copy its **DUID** (Device Unique Identifier) --- ## ⚙️ Detailed Configuration Steps 1. **Access DDNS Configuration** - Navigate to: `Advanced Applications` → `Dynamic DNS` 2. **Fill in DDNS Parameters** - **Service Provider**: Select DNSPod (or Alibaba Cloud, etc.) - **Domain Name**: Enter complete domain (e.g., `dpit-v2-v6-ikuai-nas.lab00.com`) - **Main Domain**: Can be left empty - **TOKEN ID** and **TOKEN**: Enter credentials from DNSPod - **Record Type**: Select **IPv6** - **Client DUID**: Paste previously copied device DUID - **Resolution IP Type**: Select **Interface IP** 3. **Save and Enable** - Auto-enables after saving - Refresh page to check update status 4. **Verify Configuration** - Check if record auto-updates in DNSPod backend - Access device using domain + port (e.g., `[domain]:51304`) --- ## 🔒 Security Note If ACL firewall isolation is configured, you need to open the corresponding port in firewall rules (such as port 51304 in the example). --- ## 🆚 Comparison Analysis | Feature | Traditional DDNS | iKuai DDNS | |---------|------------------|------------| | Installation Location | Each device separately | Unified router config | | Configuration Complexity | # of devices × configs | One-time configuration | | Maintenance Cost | High (multi-point) | Low (single-point) | | IPv6 Compatibility | Requires device support | Native support | | Use Case | Single device | Multi-device networks | --- ## 🎯 Typical Use Cases 1. **Remote Game Streaming**: Works with Sunshine + Moonlight for IPv6-based public network streaming 2. **Remote NAS Access**: Bind fixed domain names to Synology and other NAS devices 3. **Home Servers**: Unified management of external access for multiple home servers 4. **IoT Device Management**: Provide stable external access for smart home devices --- ## ✅ Summary iKuai OS's IPv6 DDNS functionality greatly simplifies dynamic domain configuration in multi-device environments through router-level unified management. In the IPv6 era, where each device has an independent public address, this centralized management approach demonstrates significant advantages, especially suitable for users with multiple devices requiring external network access. --- ## 🏷️ SEO Keywords iKuai DDNS, IPv6 Dynamic DNS, Soft Router Configuration, iKuai OS Tutorial, IPv6 DDNS Setup, DNSPod DDNS, Router DDNS, LAN IPv6, Remote NAS Access, Dynamic Domain Resolution
