# E ## Egress In computer networking, egress refers to the flow of data packets from a network or device to another network or the internet. It is the opposite of ingress, which refers to the flow of data packets into a network or device.Egress traffic is typically generated by user devices or applications and travels through the network to reach its intended destination. ## Elastic IP EIP stands for Elastic IP. It is a static, public IPv4 address that can be assigned to a cloud resource, such as an instance in a cloud computing environment, and then quickly reassigned to another resource if needed.An EIP is called "elastic" because it can be easily allocated and released, allowing it to be quickly reassigned to another resource in the same region. This makes it useful for scenarios where resources need to be replaced or scaled up or down on demand. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
