What is CGNAT ? (Carrier-grade Network Address Translation)
- Carrier-grade Network Address Translation (CGNAT) is an IP address provisioning method using a private IP address block used by Internet Service Providers due to the declining availability of public IPv4 addresses. As of 2020, PLDT has been transitioning both DSL and Fibr customers to CGNAT through modem/ONU firmware updates for existing users. New customers are automatically put under CGNAT. Additionally, service requests involving the resetting of the modem/ONU will also put the customer under CGNAT.
How to Tell If You Have Carrier Grade NAT (CGNAT)
Method 1.
Open CMD and Run Tracert Command (Copy the Command Bellow and Paste it in CMD)
Example of CGNAT:tracert 9.9.9.9
Method 2.
Log in to your router's gateway and go to wan status, then check your vlan to see whether it's 1030, and if it is, you have CGNAT.
