VPC Network Address Translation When you associate an ENI with a public IP address, the ENI maintains its private IP address. Associating a public IP with an ENI doesn’t reconfigure the ENI with a new address. Instead, the Internet gateway maps the public IP address to the ENI’s private IP address using a process called network address translation (NAT). When an instance with a public IP connects to a host on the Internet, the host …
Overview of an Amazon Virtual Private Cloud Virtual service provides the networking layer of EC2. A VPC is a virtual network that can contain EC2 instances as well as network resources for other AWS services. By default, every VPC is isolated from all other networks. You can, however, connect your VPC to other networks, including the Internet and other VPCs. In addition to EC2, VPCs are foundational to many AWS services, so understanding how they …

DHCP DHCP Request/Reply Messages a device that already has an IP address can use the simple request/reply exchange Message to get other configuration parameters from a DHCP server. When the DHCP client receives a DHCP offer, the client immediately responds by sending back a DHCP request packet. Devices that aren’t using DHCP to accumulate IP addresses can still utilize DHCP’s other configuration capabilities. A client can broadcast a DHCP INFORM message to request that any …
Dynamic Host Configuration Protocol How Dynamic Host Configuration Protocol (DHCP) Works is a client/server protocol that gives an IP address to an IP host. additionally, to the IP address, the DHCP server also provides configuration-related information like the default gateway and subnet mask. When a Dynamic Host Configuration Protocol client device boots up, it participates in traffic broadcasting. DHCP can assign IP configuration to hosts connecting to a network. The distribution of IP configuration to …
