What are the advantage of private ip ?
No one can hack you through the private ip.Since your network will be Double NAT by unifi network.
And no more advantage compare to public ip.
Only disadvantage for private ip.
And i also ask Chatgpt after i wrote the word above.

For regular users, the benefits of having your Internet connection run through CGNAT (using private IP addresses) are mainly about efficiency and cost:
Better Use of Limited IPs: Your ISP can share a single public IP address among many customers. This smart use of addresses means they can keep providing service even when public IPs are in short supply.
Cost Savings: Because fewer public IP addresses need to be managed or purchased, your ISP can offer reliable internet at lower costs, which often means more affordable service for you.
Added Basic Security: Your personal device's private IP isn’t directly exposed to the public internet. This extra “shield” can help reduce the risk of unsolicited attacks on your home network.
Overall, while CGNAT might sometimes affect things like hosting your own server or port forwarding, for most home users it makes your connection reliable, cost-effective, and a bit more secure.
So conclusion no advantage for using private ip.

Advantage for using ISP Public IP (Anwser by ChatGPT)

Using a public IP address instead of a private IP (CGNAT) has several advantages, especially for users who need more control over their internet connection. Here’s how public IPs compare:
Advantages of Public IP Over Private IP (CGNAT)
Direct Access to Your Devices
With a public IP, your devices can be accessed directly from the internet, making it easier to host services like websites, game servers, remote desktop connections, or CCTV cameras without extra workarounds.
With CGNAT, inbound connections are blocked unless the ISP provides a way to forward ports.
No Issues with Port Forwarding
Public IPs allow full control over port forwarding, letting you set up services like VPNs, home servers, or custom applications.
CGNAT usually blocks this functionality because multiple users share the same public IP.
Better Online Gaming Experience
Some online multiplayer games require NAT Type 1 or 2 for optimal connections. CGNAT often forces a strict NAT Type 3, which can cause connection issues, longer matchmaking times, or even prevent online play.
With a public IP, gaming consoles and PCs can connect directly to other players, improving performance.
Improved Peer-to-Peer (P2P) Performance
Services like torrenting, file sharing, and decentralized applications work better with a public IP because they rely on direct peer connections.
Under CGNAT, these services might experience slow speeds or connection failures.
Avoid Shared IP Restrictions
Many websites and services block or impose limits on users from CGNAT networks because multiple people share the same IP.
If someone on the same CGNAT IP is banned from a website or flagged for suspicious activity, you might also get blocked.
Easier Remote Access & IoT Device Management
Public IPs allow direct control of smart home devices (e.g., security cameras, smart thermostats, and automation systems) from anywhere without relying on third-party cloud services.
CGNAT makes this more complicated and sometimes impossible.
When is CGNAT Acceptable?
If you only browse the web, watch videos, or use social media, CGNAT won’t make a noticeable difference.
If your ISP offers IPv6, many of these limitations disappear since IPv6 allows every device to have a unique address.
Final Thoughts
If you need remote access, better gaming, P2P performance, or hosting services, a public IP is the better option. If your ISP only provides CGNAT, you might have to request a static or dynamic public IP as an add-on service.
Last Edit:
So far i see some people under CGNAT private ip will get lower qos connection compare to public ip,as sometimes CGNAT gateway might have congestion or else issue.
