IP address reported by OS different from IP address reported by router

My notebook computer does not have an RJ45 port and I have to use an USB-to-Ethernet adapter to connect my machine to the LAN port of my router.

My operating system is Microsoft Windows 10 and according to the information provided by the OS, my IP address is:

Adapter Type: Ethernet 802.3

Product Type: ASIX AX88179 USB 3.0 to Gigabit Ethernet Adapter

Installed: Yes

Service Name: AX88179

IP Address: 192.168.0.186

IP Subnet: 255.255.255.0

Default IP Gateway: 192.168.0.1

DHCP Enabled: Yes

DHCP Server: 192.168.0.1

However, after I have logged into my router that is directly connected to my ISP, it gives me the following information:

WAN

IP Address: 172.20.34.33

Dynamic IP

Subnet Mask: 255.255.254.0

Default Gateway: 172.20.34.1

DNS Server: 1.1.1.1

I would appreciate it if someone could explain to me the differences in the IP addresses.
