A Practical Approach: Use Free Tunneling Services
If your goal is to host your own services, a free domain might not always be the best solution due to restrictions like the inability to file for web service licenses (ICP filing). Instead, consider free tunneling services that allow access to internal services from external networks. This is particularly useful for:
- IPv6 Setup: Domains configured to IPv6.
- Non-Web Services: Hosting services like SSH or MQTT on VPS.
Conclusion
Each of these platforms has its unique features, from extensive subdomain support to simplified registration processes. Depending on your use case—be it for a personal project or a home network—these free options can help you get started without any upfront cost. Choose wisely and enjoy the perks of free domain services!
