Integer to IPv4 Converter

Convert 32-bit integers to IPv4 addresses with detailed breakdown

What is Integer to IPv4 Conversion?

Integer to IPv4 conversion transforms a 32-bit integer value back into a standard IPv4 address format. This is the reverse operation of IPv4 to integer conversion and is commonly used when retrieving IP addresses from databases, APIs, or network calculations where IPs are stored as integers for efficiency and range operations.

How Does Integer to IPv4 Conversion Work?

The conversion process extracts each octet from the 32-bit integer using bitwise operations. Here's the step-by-step process:

  1. Validate the input: Ensure the integer is between 0 and 4,294,967,295 (2³² - 1)
  2. Extract octets using bit shifting: Use right shift and masking to get each 8-bit segment
  3. Calculate octets: Octet1 = (int >> 24) & 255, Octet2 = (int >> 16) & 255, etc.
  4. Format as IPv4: Join the four octets with dots (e.g., 192.168.1.1)
  5. Determine network class: Classify the IP address based on the first octet

This conversion is essential for network programming and database operations involving IP addresses!
