Network 172.20.15



The local network with the IP range starting with 172.20.15 is part of the private IP address space defined by the Internet Engineering Task Force (IETF) in RFC 1918. This range is commonly used in home and small office networks. On this page we wil explain how you can use 172.20.15.0/24 for your own home network with the correct settings.

Characteristics

The 172.20.15.0/24 range is designated for private use within local networks. It cannot be routed on the public internet, meaning these addresses are not accessible from outside the local network.

Subnet range

The subnet 172.20.15.0/24 includes IP addresses from 172.20.15.0 to 172.20.15.255. The subnet mask is 255.255.255.0.

Common usage

This IP range is often used by home routers and small office routers as the default network. Devices connected to such routers (like computers, smartphones, printers) will typically receive an IP address in this range via DHCP (Dynamic Host Configuration Protocol).

Network components

Typical setup

  • Router/Gateway - The router in such a network often has the IP address 172.20.15.1, which serves as the default gateway for other devices in the network.
  • DHCP range - A common DHCP range might be 172.20.15.2 to 172.20.15.254, dynamically assigning IP addresses to devices as they join the network.
  • Static IPs - Some devices (like printers or servers) might be assigned static IPs within this range for consistent access.

Example

Here is a typical configuration for a small home network using the 172.20.15/24 subnet:

Router IP 172.20.15.1
Laptop IP 172.20.15.2
Smartphone IP 172.20.15.3
Printer IP 172.20.15.100
Broadcast address 172.20.15.255


Advantages

  • Isolation - Being part of a private address space, the network is isolated from the public internet, providing a layer of security.
  • No conflicts - Since this range is designated for private use, there's no conflict with public IP addresses, allowing safe reuse in different private networks.

Considerations

  • NAT (Network Address Translation) - To access the internet, devices on a 172.20.15.* network use NAT, where the router translates private IP addresses to a public IP address.
  • Network segmentation - In larger networks, segmenting with different subnets (beyond just 172.20.15.*) might be necessary for better performance and management.
Overall, the 172.20.15.* network is a convenient and widely-used IP range for setting up local networks in homes and small offices due to its simplicity and effectiveness in managing multiple devices.
