The first and the last subnets obtained by subnetting a larger network have traditionally had a special designation and, early on, special usage implications. [6] In addition, IPv4 uses the all ones host address, i.e. the last address within a network, for broadcast transmission to all hosts on the link.
A virtual private cloud (VPC) is an on-demand configurable pool of shared resources allocated within a public cloud environment, providing a certain level of isolation between the different organizations (denoted as users hereafter) using the resources.
VPC is Amazon Web Services (AWS) solution for providing isolated network environments for AWS resources. IP addresses in a VPC are used for communication between resources within the VPC, as well as for communication between the VPC and the Internet. There are two types of IP addresses used in a VPC: private IP addresses and public IP addresses.
An IPv4 address is 32 bits so an n-bit CIDR prefix leaves 32 − n bits unmatched, meaning that 2 32−n IPv4 addresses match a given n-bit CIDR prefix. Shorter CIDR prefixes match more addresses, while longer prefixes match fewer. In the case of overlaid CIDR blocks, an address can match multiple CIDR prefixes of different lengths.
AWS launches Simple Notification Service (SNS), a tool to allow developers to push messages generated from an application to other systems and people (by methods such as email or webhooks).

In network security a screened subnet refers to the use of one or more logical screening routers as a firewall to define three separate subnets: an external router (sometimes called an access router), that separates the external network from a perimeter network, and an internal router (sometimes called a choke router) that separates the ...
Amazon Route 53 is a Domain Name System (DNS) service by Amazon Web Services (AWS) since 2010. The name is a possible reference to U.S. Routes, [1] and "53" is a reference to the TCP/UDP port 53, where DNS server requests are addressed. [2]
