I need to create alias Ip for my local machine, as a reference I'm using https://websiteforstudents.com/switch-static-ip-address-ubuntu-17-04-17-10/
ifconfig showing my network interface as:
wlp3s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.1.106 netmask 255.255.255.0 broadcast 192.168.1.255
inet6 fe80::b7c0:76a:d0c0:3a7b prefixlen 64 scopeid 0x20<link>
ether 6c:71:d9:21:ff:61 txqueuelen 1000 (Ethernet)
RX packets 389087 bytes 342937114 (342.9 MB)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 270723 bytes 54566302 (54.5 MB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
but when I running sudo nano /etc/network/interfaces as mentioned in the reference I see different file content:
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback
so I make a try to add interface manually to /etc/network/interfaces:
# The primary network interface
auto wlp3s0
iface wlp3s0 inet dhcp
iface wlp3s0 inet static
address 10.254.254.254/24
but it's not working when I'm running sudo ifdown wlp3s0 && sudo ifup wlp3s0 I'm getting:
ifdown: interface wlp3s0 not configured

Failed to bring up wlp3s0.
I'm a novice in this, please help me to solve the issue, thanks!
the alias must be of the form - wlp3sX:Y, where X is the physical network interface number and Y is the network interface number alias. everything is described in detail - http://drach.pro/blog/linux/item/71-ip-address-alias-on-centos-6-6 http://semenushkin.ru/2010/09/28/ifconfig-alias/
