Net-tools to iproute2

The deprecated net-tools package contains all legacy network tools such as ipconfig, route, arp, etc. Since tools from net-tools are now obsolete, it is best practice to move towards using the replacement commands provided by iproute2.

The following table maps the old net-tools commands to the new iproute2 commands.

Old net-tools	New iproute2	Description
arp	ip neighbour	Show ARP table
netstat -ln	ss -ln	Show listening ports
netstat -r	ip route	Shows routing table
netstat -i	ip -s link	shows network interface counters
netstat -g	ip maddr	Show interface group memberships
iwconfig	iw	Wireless config
iptunnel	ip tunnel	IP Tunnel configuration
nameif	ip link	Shows interfaces based on MAC address
ifconfig	ip address	Shows interface addresses
ifconfig $interface [up|down]	ip link set dev $interface [up|down]	Bring an interface up or down
ifconfig $interface $ip netmask $netmask	ip addr add $ip/$mask dev $interface	Adds a secondary IP to an interface
ifconfig $interface del $ip netmask $netmask	ip addr del $ip/$mask dev $interface	Deletes a secondary IP to an interface
route add default gw $gateway	ip route add default via $gateway	Adds a default gateway
route add -net $net netmask $netmask gw $gateway	ip route add $net/$mask via $gateway	Adds a static route via a gateway
route del -net $net gw $gateway netmask $netmask dev $device	ip route del $net/$mask via $gateway	Deletes a static route
route -n	ip route	Shows routing table

The iproute2 sub commands can be specified with the shortest unambiguous name (ie. a or addr for address).
