ifconfig / eth0 aliases vs iproute2 / ip up?

networking

The static IP address networking guide here recommends using interface aliases instead of ip add.

Comments like http://serverfault.com/a/484737 and http://inai.de/2008/02/19 make it seem like a really old deprecated mechanism.

Does anyone use ip add instead?

Either works. I use 'ip addr add' almost exclusively because it's easier to remember, and I can manually set preferredlft to divert outgoing traffic from such IP addresses, e.g. "ip addr add 2600:3c03::13:3702/64 dev eth0 preferredlft 0"
