OS: Ubuntu server 16.04.
So I changed my local IP's from class c to class a. Now I get a weird issue on the server.
(I connect to the server using the set statically IP on SSH from a local PC)
After a reboot it can't reach the WAN. if I try to ping 8.8.8.8 I get thisFrom <old class c. IP> icmp_seq=1 Destination Host Unreachable
ifconfig shows it's using the new statically set class a IP.
Temp fix:dhclient -r -v <interface> && rm /var/lib/dhcp/dhclient.* ; dhclient -v <interface>
This returns
dhclient -v <interface>

"I changed my local IP's from class c to class a"? How, exactly did you do that? It seems like network nonsense.

I changed my local network, from a class C to a class A. followed up by changing the IP of the server to a new IP on the class A range, how is this nonsense?
