ip addr - sets and displays ip addresses
ip route - sets and displays routes (plain 'route' can't display lots of
advanced routing info that is in use today)
ip link - sets and displays interface link information

ip addr and ip link essentially replace ifconfig.  They also aren't
cutting off interface names at 9 characters the way ifconfig does.

For example:
ifconfig eth0 down = ip link set eth0 down
ifconfig eth0 multicast = ip link set eth0 multicast on
ifconfig eth0 -multicast = ip link set eth0 multicast off
ifconfig eth0 10.1.2.3 netmask 255.0.0.0 = ip addr flush dev eth0;ip addr add dev eth0 10.1.2.3/8
ifconfig eth0 add 10.1.2.4/8 = ip addr add dev eth0 10.1.2.4/8

It also replaces ifrename:
ifrename -i eth0 -n ethdsl = ip link set eth0 name ethdsl

And of course route:
route add 10.0.0.0 netmask 255.0.0.0 dev eth0 = ip route add 10.0.0.0/8 dev eth0
