To start, I'll say it's been nearly 2 decades since I've fiddled with *nix, and that was OBSD.. so to say I'm rusty is an understatement... And I'm new to Rpi.
So I've edited the /etc/network/interfaces file, and added my desired static IP and netmask, I exit, I pull the interface down and back up, and it is set and working.. I reboot, and I have some weird IP again, the file is as I left it...
I must be missing something somewhere, what is it?
/etc/network/interfaces is
GNU nano 2.2.6 File: /etc/network/interfaces
auto lo
iface lo inet loopback
auto eth0
allow-hotplug eth0
iface eth- inet manual
allow-hotplug wlan0
iface wlan0 inet manual
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
allow-hotplug wlan1
iface wlan1 inet manual
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
/etc/dhcpcd.conf is
interface eth0 static ip_address= 192.168.1.250/16
hostname

option domain_name_servers, domain_name, domain_search, host_name

OK, I removed all the comments that seemed to be offensive to formatting
