1.1 What is a subnet

A subnet is a network of private addresses assigned to a network interface which is connected to a private network. A subnet is closely linked to the VPC Network and inherits its location (Region).
 
configuration IP / CIDR address [1] available network hosts IP range
default 192.168.0.0 / 24 28 = 256 from 192.168.0.0
to 192.168.0.255
advanced 192.168.0.0 / 16 216 = 65.536 from 192.168.0.0
to 192.168.255.255
172.16.0.0 / 12 220 = 1.048.576 from 172.16.0.0
to 172.31.255.255
10.0.0.0 / 8 224 = 16.777.216 from 10.0.0.0
to 10.255.255.255
1. Classless Inter-Domain Routing

Example of manual change of DHCP (Dynamic Host Configuration Protocol)

Range start - The starting IP and must be within the chosen IP range.
192.168.0.10

Number of IPs - Indicates the number of IPs you want to use starting from the range start.
15

In this example, therefore, you will have the following IP addresses:
entering 192.168.0.10
entering 192.168.0.11
...
...
entering 192.168.0.23
entering 192.168.0.24

Route - With this instruction, you can use DHCP to assign static routes to all servers on your network, allowing them to reach networks outside the usual broadcast domain.
10.0.0.7 gw 192.168.0.11
10.0.0.6 gw 192.168.0.11
172.16.0.0/16 gw 192.168.0.100

DNS - By specifying this directive, all servers will use these addresses for name resolution. Depending on your network configuration, you can specify private addresses (if you have a local resolver) or public addresses such as those of Google or Cloudflare.
192.168.0.150
192.168.0.151
 
The subnet service is provided at no extra cost.
