Inspecting IP Addresses

VMware recommends that you use the ip or ss commands as the ifconfig and netstat commands are deprecated.

To display a list of network interfaces, run the ss command. Similarly, to display information for IP addresses, run the ip addr command.

Examples:

USE THIS IPROUTE COMMAND     INSTEAD OF THIS NET-TOOL COMMAND
ip addr                     ifconfig -a
ss                             netstat
ip route                     route
ip maddr                     netstat -g
ip link set eth0 up         ifconfig eth0 up
ip -s neigh                    arp -v
ip link set eth0 mtu 9000    ifconfig eth0 mtu 9000

Use the ip route version of a command instead of the net-tools to get accurate information:

ip neigh
198.51.100.2 dev eth0 lladdr 00:50:56:e2:02:0f STALE
198.51.100.254 dev eth0 lladdr 00:50:56:e7:13:d9 STALE
198.51.100.1 dev eth0 lladdr 00:50:56:c0:00:08 DELAY

arp -a
? (198.51.100.2) at 00:50:56:e2:02:0f [ether] on eth0
? (198.51.100.254) at 00:50:56:e7:13:d9 [ether] on eth0
? (198.51.100.1) at 00:50:56:c0:00:08 [ether] on eth0

Important: If you modify an IPv6 configuration or add an IPv6 interface, you must restart systemd-networkd. Traditional methods of using ifconfig commands will be inadequate to register the changes. Run the following command instead:

systemctl restart systemd-networkd
