Understanding RFC 3514: The Internet Evil Bit - Kate On AI
What is RFC 3514? The RFC proposes the addition of a single bit, known as the “Evil Bit,” in the IPv4 header. This bit, when set to ‘1’, would indicate that the packet being transmitted is intended for malicious purposes. Conversely, when set to ‘0’, the packet would be considered benign. The primary goal of […]
A Concrete Definition of an AI Agent
