In AWS RDS, the internal IP address of a MySQL instance is not directly shown in the RDS dashboard. However, you can determine the internal IP by following these steps:

1. **Find the RDS Instance's VPC:**
   - Go to the **RDS Dashboard** in AWS Management Console.
   - Select your MySQL instance.
   - Under the **Connectivity & security** tab, note the **VPC ID** and **Subnet Group** associated with your instance.

2. **Go to the EC2 Dashboard:**
   - In the AWS Management Console, navigate to the **EC2 Dashboard**.
   - On the left menu, under **Network & Security**, select **Network Interfaces**.

3. **Filter by VPC:**
   - Use the **VPC ID** from the RDS instance to filter the network interfaces.
   - Look for the network interface that is associated with the same **Subnet Group** as your RDS instance.

4. **Find the Private IP:**
   - The associated network interface will have a **Primary private IPv4 address** listed. This is the internal IP of your MySQL instance.

This method requires you to correlate the VPC and subnet information from the RDS instance with the corresponding network interface in the EC2 dashboard.
