How to add multiple IPv4/v6 to VPS/server (bind multiple IPs to a single network card)

Many times when you buy a VPS or independent server, you will find that the multiple IPs assigned by default are unavailable, or the project expansion requires adding multiple IPs. At this time, we need to manually modify and configure new multiple IPs for the server. Here we take the Debian operating system as an example to briefly describe the operation process, for reference only!

Open file for editing:

vi /etc/network/interfaces

Add IPv4, take adding 5 (/29) as an example:

auto lo

iface lo inet loopback

auto enp3

iface enp3 inet static

address 192.187.88.21/29 (your own IP segment)

gateway 192.187.88.20 (server’s gateway)

dns-nameservers 8.8.8.8 8.8.4.4 (DNS)

auto enp3:0

iface enp3:0 inet static

address 192.187.88.22/29

auto enp3:1

iface enp3:1 inet static

address 192.187.88.23/29

auto enp3:2

iface enp3:2 inet static

address 192.187.88.24/29

auto enp3:3

iface enp3:3 inet static

address 192.187.88.25/29

Add IPv6:

iface enp3 inet6 static

address 2604:2048:a:12a::2/64

gateway 2604:2048:a:12a::1

up ip addr add 2604:2048:a:12a::1024/64 dev enp3

up ip addr add 2604:2048:a:12a::1025/64 dev enp3

Pay attention to the network card name and gateway, don’t make a mistake;

IPv4 and IPv6 can be configured a lot, copy it and change the number (such as auto enp3:0).

Finally, restart the network:

systemctl restart networking
