IP spoofing is a technique used in network communications to falsify the source IP address of a packet, making it appear as if it originated from a different IP address or location than its actual source. In other words, IP spoofing involves manipulating the IP header of a network packet to deceive the recipient about the true origin of the communication.

Here's how IP spoofing works:

  1. Normally, when a device sends a packet over a network, it includes its source IP address in the IP header. This source IP address is used by the recipient to determine where the packet originated from.
  2. In an IP spoofing attack, an attacker modifies the source IP address in the packet header to a different IP address. This IP address can be a randomly chosen address or the address of a trusted entity that the attacker wants to impersonate.
  3. The attacker then sends the spoofed packet to the target or a device in the network, making it appear as if the packet came from the falsified source IP address.
  4. The recipient, based on the spoofed IP address, may believe that the packet is coming from a legitimate source and respond accordingly.
