Hello All, I need help to add new IP address which I got from the AWS to configure on my ISPConfig server. The primary IP from AWS works perfectly fine and given below is the network configuration file on server. I need to add secondary IP on same primary network eth0 as eth0:0 or eth0:1 root@ip-172-31-14-170:/etc# vi /etc/network/interfaces # interfaces(5) file used by ifup(8) and ifdown(8) auto lo iface lo inet loopback auto eth0 iface eth0 inet dhcp I already have added the new IP address on server through ISPconfig >> System >> Server IP addresses >> Add new IP address but I can not see it in on shell or IP does not ping.
