Amazon Virtual Private Cloud (VPC) is a commercial cloud computing service that provides a virtual private cloud, by provisioning a logically isolated section of Amazon Web Services (AWS) Cloud. [1] Enterprise customers can access the Amazon Elastic Compute Cloud (EC2) over an IPsec based virtual private network .

Amazon Web Services launched Amazon Virtual Private Cloud on 26 August 2009, which allows the Amazon Elastic Compute Cloud service to be connected to legacy infrastructure over an IPsec VPN. [1] [2] In AWS, the basic VPC is free to use, with users being charged by usage for additional features.
Some large / 8 blocks of IPv4 addresses, the former Class A network blocks, are assigned in whole to single organizations or related groups of organizations, either by the Internet Corporation for Assigned Names and Numbers (ICANN), through the Internet Assigned Numbers Authority (IANA), or a regional Internet registry.
Although it is technically possible to use smaller subnets, [13] they are impractical for local area networks based on Ethernet technology, because 64 bits are required for stateless address autoconfiguration. [14] The Internet Engineering Task Force recommends the use of / 127 subnets for point-to-point links, which have only two hosts. [15] [16]
Classless Inter-Domain Routing (CIDR / ˈ s aɪ d ər, ˈ s ɪ-/) is a method for allocating IP addresses for IP routing.The Internet Engineering Task Force introduced CIDR in 1993 to replace the previous classful network addressing architecture on the Internet.
A wildcard mask is a mask of bits that indicates which parts of an IP address are available for examination. In the Cisco IOS, [1] they are used in several places, for example:
In addition to certification obtained by taking courses and/or passing exams (and in the case of CISSP and others noted below, demonstrating experience and/or being recommended or given a reference from an existing credential holder), award certificates also are given for winning government, university or industry-sponsored competitions ...
