  4. You can copy the octal representation of the IP address by clicking the "Copy" button.

How It's Done

The core logic of the IP to octal conversion formula is:

  1. Treat each decimal octet of the IP address as a base 256 number.
  2. Convert each decimal octet:
    a) Convert the decimal number to an octal string using decimal.toString(8).
    b) This transforms each octet to an octal string.
  3. Based on the position and weight of each octet in the IP address, calculate the total octal number value.
    The weights from highest to lowest are a, b, c, d.
  4. The formula is:
    octal = (a _ 256^3) + (b _ 256^2) + (c \* 256^1) + d
  5. Where a, b, c, d represent the octal strings of the 4 octets.
  6. Calculate the final octal number based on the weights.

In summary, the key logic is:

  • Treat each decimal octet as base 256.
  • Convert to an octal string.
  • Calculate the final octal number by the weights.

This conversion elegantly maps the 4 decimal octets of the IP address into a single octal number, while retaining the octet position weights.


The IP address uses base 256, so each octet has a range of 0 to 255. When converting to octal, using powers of 8 would truncate the octet values. Powers of 256 match the base 256 structure to preserve the full 0-255 range of each octet.

Here are some examples of how to convert IP addresses to octal format in different programming languages:


ip_address = ""
parts = ip_address.split(".")
octal_parts = []
for part in parts:
    decimal = int(part)
    octal = oct(decimal)[2:]
octal_address = ".".join(octal_parts)


#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <math.h>

unsigned int convert_ip_to_octal(char *ip_address) {
    int a, b, c, d;
    sscanf(ip_address, "%d.%d.%d.%d", &a, &b, &c, &d);
    return (a * pow(256, 3)) + (b * pow(256, 2)) + (c * pow(256, 1)) + d;

int main() {
    char ip_address[16];
    printf("Enter IP address: ");
    fgets(ip_address, 16, stdin);
    ip_address[strlen(ip_address) - 1] = '\0';
    unsigned int octal = convert_ip_to_octal(ip_address);
    printf("Octal representation: %o\n", octal);
    return 0;


function convert_ip_to_octal(ip_address) {
  let parts = ip_address.split(".");
  let octal_parts = parts.map((part) => {
    let decimal = parseInt(part);
    let octal = decimal.toString(8);
    return octal.padStart(3, "0");
  let octal_address = octal_parts.join(".");
  return octal_address;
let ip_address = "";
let octal_address = convert_ip_to_octal(ip_address);


public class IpToOctalConverter {
    public static void main(String[] args) {
        String ip_address = "";
        String[] parts = ip_address.split("\\.");
        String[] octal_parts = new String[4];
        for (int i = 0; i < parts.length; i++) {
            int decimal = Integer.parseInt(parts[i]);
            String octal = Integer.toOctalString(decimal);
            octal_parts[i] = ("000" + octal).substring(octal.length());
        String octal_address = String.join(".", octal_parts);


function convert_ip_to_octal($ip_address) {
    $parts = explode(".", $ip_address);
    $octal_parts = array();
    foreach ($parts as $part) {
        $decimal = (int) $part;
        $octal = decoct($decimal);
        $octal_parts[] = str_pad($octal, 3, "0", STR_PAD_LEFT);
    $octal_address = implode(".", $octal_parts);
    return $octal_address;
$ip_address = "";
$octal_address = convert_ip_to_octal($ip_address);
echo $octal_address;
