Who Assigns a private IP address to our Laptops?
As we know, a Private IP address may assigned to a device even if it is not connected to the router. Who assigns this private IP address to our device (i.e., Laptop, PC).

The DHCP of mobile hotspots has its own NAT, which is a Type 2, B, and Moderate one. EVO WiFi also acts as a mobile hotspot.
