You Should Know:
Understanding IPv4 and IPv6 is crucial for networking professionals. Below are some practical commands and steps to work with these protocols:
IPv4 Commands:
1. Check IP Address (Linux):
ifconfig
or
ip addr show
2. Ping an IPv4 Address:
ping 192.168.1.1
3. Configure a Static IPv4 Address (Linux):
Edit the network configuration file:
sudo nano /etc/network/interfaces
Add the following lines:
auto eth0 iface eth0 inet static address 192.168.1.100 netmask 255.255.255.0 gateway 192.168.1.1
Restart the network service:
sudo systemctl restart networking
IPv6 Commands:
1. Check IPv6 Address (Linux):
ifconfig
or
ip -6 addr show
2. Ping an IPv6 Address:
ping6 2001:db8::1
3. Configure a Static IPv6 Address (Linux):
Edit the network configuration file:
sudo nano /etc/network/interfaces
Add the following lines:
auto eth0 iface eth0 inet6 static address 2001:db8::100 netmask 64 gateway 2001:db8::1
Restart the network service:
sudo systemctl restart networking
Troubleshooting Commands:
1. Check Routing Table:
netstat -r
or
ip route show
2. Trace Route (IPv4):
traceroute 192.168.1.1
3. Trace Route (IPv6):
traceroute6 2001:db8::1
