ifconfig eth0 172.16.254.80 netmask 255.255.255.240 route add default gw 172.16.254.1
I am getting Network is unreachable.
ipcalc -nbp 172.16.254.80 255.255.255.240 PREFIX=28 BROADCAST=172.16.254.95 NETWORK=172.16.254.80
so 172.16.254.1 is not in your network and thus not reachable
And I'm a dunce cap...sorry 255.255.255.0 should be the mask!
Thanks for the math lesson!
