Show activity on this post. forgot my comment, in the first case you have an virtual interface alias ifconfig eth0:1 192.168.4.1/24 up and in the second case you have an secondary ip address ip addr add 192.168.4.1/24 dev eth0. but in both case are secondary address, the first is in the old style and second is new configuration style using the ...
02.07.2013 · Where “:X” is the device (interface) number to create the aliases for interface eth0.For each alias you must assign a number sequentially. For example, we copying existing parameters of interface “ifcfg-eth0” in virtual interfaces called ifcfg-eth0:0, ifcfg-eth0:1 and ifcfg-eth0:2.Go into the network directory and create the files as shown below.
