You can use your local router’s internal IP address to test if a port is blocked by your local network, internet service provider (ISP), or virtual private network (VPN). Most operating systems (OSs) – Windows, macOS, Linux, BSD, etc. – with a graphical user interface (GUI) have pre-installed software that can give you this information. But if you’re working in the command line interface (CLI) on a related task, such as examining a traceroute/tracepath, knowing commands that can provide the same information improves your workflow.
Below we cover how to get your local router IP address in the terminal depending on your OS:
These commands may display multiple IP addresses if you’re connected to a VPN. Disconnect from the VPN and rerun the command to be sure which is your local router IP. On home networks, visit the IP address in your web browser (e.g. https://192.168.0.3) to ensure it displays the login page for your home router.
Get Your Local Router IP Address
Most OSs – netstat
netstat command, pre-installed on most OSs, displays current TCP and UDP network connections with related processes. Netstat with the
-r flag provides the IP routing table and internal router IP address.
The results will be the IP address in the first (Destination) column:
Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface 192.168.1.1 0.0.0.0 255.255.255.0 U 0 0 0 eno2
You can use
route for the same results:
Windows – ipconfig
ipconfig command will show your local network connections and information.
Your local router’s internal IP will show to the right of Default Gateway under your current network (wireless, ethernet, etc.):
Default Gateway . . . . . . . . . : 192.168.0.1
Linux – ip r
ip command shows similar info to
ifconfig and supersedes
netstat (part of
net-tools) on some Linux OSs. Replacing
r filters the results to the IP (DNS names instead of host addresses) and interfaces while
| grep filters the output to only rows including “default”.
ip r | grep default
The results will show the IP among related information:
default via 192.168.0.10 dev eno2 proto metric 100
You can use the following commands for the same results:
ip r list | grep default
ip route | grep default
