IPv4 Address Formats: Decimal, Binary, Hex, and Octal
Key Takeaways
- An IPv4 address is a 32-bit number that can be represented in dotted decimal, binary, hexadecimal, and integer formats.
- Understanding different IPv4 representations is essential for network debugging, firewall rules, and low-level protocol analysis.
- All address conversion happens in your browser — your IP addresses are never transmitted to any server.
IPv4 addresses are most commonly written in dotted-decimal notation (192.168.1.1), but the underlying 32-bit integer can be expressed in many formats. Binary representation reveals subnet boundaries, hexadecimal is used in packet captures and memory dumps, and integer format appears in some database storage schemes. Converting between these formats is a frequent task in network administration and security analysis.
There are approximately 4.3 billion possible IPv4 addresses (2^32), with less than 15% remaining unallocated.

Key Concepts
Dotted Decimal Notation
The standard format (192.168.1.1) represents each of the four octets as a decimal number (0-255) separated by dots. This is the most human-readable format used in configuration.
Binary Representation
Each octet is an 8-bit binary number. 192.168.1.1 = 11000000.10101000.00000001.00000001. Binary is essential for understanding subnetting and mask operations.
Hexadecimal Format
Each octet as two hex digits: 192.168.1.1 = C0.A8.01.01 or 0xC0A80101. Hex appears in packet captures (Wireshark), memory addresses, and low-level network programming.
Integer (Long) Format
The entire 32-bit address as a single integer: 192.168.1.1 = 3232235777. Some databases store IP addresses as integers for efficient range queries and indexing.
Pro Tips
Use binary format to visualize subnet boundaries — the network/host boundary falls at the subnet mask's transition from 1s to 0s.
Store IPv4 addresses as 32-bit integers in databases for 4x storage savings and faster range queries compared to string storage.
Be aware that some systems interpret leading zeros as octal — 010.010.010.010 may be parsed as 8.8.8.8, not 10.10.10.10.
Use hex format when analyzing network packets in Wireshark or writing raw socket programs.
All IPv4 address conversion is performed entirely in your browser. Your IP addresses and network information are never transmitted to any external server.
