# 🛣️ `route` Command Documentation
|
||
|
||
The `route` command is used to view and manipulate the IP routing table in Linux systems. Below is a concise guide to listing, adding, and deleting routes using `route`.
|
||
|
||
---
|
||
|
||
## 📋 View Routing Table
|
||
|
||
```bash
|
||
route -n
|
||
```
|
||
|
||
* **Description**: Displays the kernel routing table.
|
||
* **`-n`**: Shows numerical addresses instead of resolving hostnames (faster and cleaner).
|
||
|
||

|
||
|
||
## ➕ Add Routes
|
||
|
||
### Add a Network Route
|
||
|
||
```bash
|
||
route add -net 10.10.10.0 netmask 255.255.255.0 gw 192.168.1.1
|
||
```
|
||
|
||
* **`-net 10.10.10.0`**: Specifies the network address.
|
||
* **`netmask 255.255.255.0`**: Defines the subnet mask for the network.
|
||
* **`gw 192.168.1.1`**: Sets the gateway through which packets will be routed.
|
||
|
||
### Add a Default Gateway
|
||
|
||
```bash
|
||
route add default gw 192.168.1.1
|
||
```
|
||
|
||
* **default**: Indicates this is the default route.
|
||
* **`gw 192.168.1.1`**: The default gateway IP address for all traffic not destined for a known network.

## ❌ Delete Routes
|
||
|
||
### Delete a Network Route
|
||
|
||
```bash
|
||
route del -net 10.10.10.0 netmask 255.255.255.0
|
||
```
|
||
|
||
* Removes the specified network route.
|
||
|
||
### Delete the Default Route
|
||
|
||
```bash
|
||
route del default
|
||
```
|
||
|
||

## 📎 Notes
|
||
|
||
* These commands typically require **superuser (root)** privileges. Use `sudo` if needed:
|
||
|
||
```bash
|
||
sudo route add ...
|
||
```
|
||
|
||
* Consider using `ip route` instead of `route`, as `route` is deprecated on some modern distributions:
|
||
|
||
```bash
|
||
ip route show
|
||
```
|
