# Internet & IP

## Internet Connection <a href="#internet-connection" id="internet-connection"></a>

You can quickly check the mobile connection status on the front page and Mobile interface.

* After successfully setting up an Internet connection on the mobile modem:
  * The "SIM card" and "Mobile Connection" display "Connected" on the front page.
  * The "Network > IPv4 Upstream" section and the Mobile interface show the IPv4 address, RX/TX stream, and connection uptime.
* Go to "Network > Diagnostics" and use the "IPv4 Ping" tool to check your internet connectivity. When the mobile signal is fair/strong, and there is no internet interruption, the ping tool should return "0% packet loss."

## Mobile IP

The "Network > IPv4 Upstream" section shows on the front page, and the Mobile interface under "Network > Interfaces" displays the IPv4/6, DNS, and gateway of the mobile internet connection.

### **Public VS Private IP**

The mobile carrier typically assigns a private IP address for the mobile connection. A private IP does not traverse the Internet and cannot be used for remote access. Check out the [IP and DNS](https://how.router.works/net/traffic/ip-dns) tutorials.

Below are the standard formats of private IP addresses:

* 10.0.0.0 to 10.255.255.255
* 172.16.0.0 to 172.31.255.255
* 192.168.0.0 to 192.168.255.255
* 100.64.0.0 to 100.127.255.255 (Carrier-Grade)
