What's the point of the "extras"?
I was hoping to just add bandwidth to my Linode, since I have no need for so much RAM, but it seems I may as well just upgrade and take RAM I don't need
The reason you'd want to use Extras is if you need a quick fix and can't afford the downtime to be relocated to a server that hosts different plans. Upgrading/downgrading requires your server to be moved to a different host, but extras just require a reboot. Okay thanks for the quick response.
Does upgrading change your IP address?
