About IPv4

IPv4 provides packet addressing and routing across interconnected networks. Its header fields expose delivery limits, fragmentation behavior, and the next-layer protocol carried in the packet.

IPv4 is the most broadly deployed internetwork protocol. Its header includes routing and fragmentation controls that are critical for packet analysis and troubleshooting.

IPv4 Header Structure

Version + IHL: IP version and header length.
Total Length + Identification + Flags/Fragment Offset: packet size and fragmentation control.
TTL + Protocol + Header Checksum: forwarding lifetime, next protocol, and header integrity.
Source IP + Destination IP: sender and receiver addresses.

Why Decode IPv4 Packets

Decode IPv4 packet headers from hex, including fragmentation, TTL, protocol, and addressing.
