Internal Ranges For Use Internally

From PedrosBrainDump

For internal networks, the private IP address ranges specified by RFC 1918 are typically used. These ranges are reserved for private use, meaning they are not routed on the public internet. The three main private IP address ranges you can use for internal networks are:

  1. Class A:
    • Range: 10.0.0.0 to 10.255.255.255
    • Subnet mask: 255.0.0.0 (or /8)
  2. Class B:
    • Range: 172.16.0.0 to 172.31.255.255
    • Subnet mask: 255.240.0.0 (or /12)
  3. Class C:
    • Range: 192.168.0.0 to 192.168.255.255
    • Subnet mask: 255.255.0.0 (or /16)

These IP ranges can be used freely within your internal network and can be subnetted further depending on your needs. If you need more isolation or have multiple departments, you might break them down into smaller subnets.

Do you have a specific use case in mind, like a certain type of network or device setup you're working with?
