## Method 1:
Open a command prompt, run ``tracert -4 beammp.com``. This will output a series of network hops. Wait for the operation to finish (may take up to 30 hops). Check the first few IP addresses after the IP of your Router/Modem/Gateway.
If multiple IP addresses within the range of ``100.64.x.x``-``100.127.x.x`` or ``10.xx.xx.xx`` appear after the first hop, you are most likely behind a CGNAT.
The first hop is your Router/Modem/Gateway and differs between Devices.
!!!Note Note
The first hop will be your Router/Modem/Gateway and differs between Devices.
The official ranges for local networks are as follows: ``10.0.0.xxx`` - ``192.168.xxx.xxx`` - ```172.16.xxx.xxx``
## Method 2:
Find out the WAN IP on your router by looking it up on its interface. Compare it to the IP posted on e.g. https://whatsmyip.org . If they are NOT the same, you are behind a CGNAT.
