In the Internet addressing architecture, the Internet Engineering Task Force (IETF) and the Internet Assigned Numbers Authority (IANA) have reserved various Internet Protocol (IP) addresses for special purposes. [1]
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.
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.
Link-local addresses may be assigned manually by an administrator or by automatic operating system procedures. In Internet Protocol (IP) networks, they are assigned most often using stateless address autoconfiguration, a process that often uses a stochastic process to select the value of link-local addresses, assigning a pseudo-random address that is different for each session.
IP packets originating from or addressed to a private IP address cannot be routed through the public Internet. Private addresses are often seen as enhancing network security for the internal network since use of private addresses internally makes it difficult for an external host to initiate a connection to an internal system.
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]
For IPv4, no black hole address is explicitly defined, however the reserved IP addresses can help achieve a similar effect. For example, 198.51.100.0 / 24 is reserved for use in documentation and examples [ 2 ] ; while the RFC advises that the addresses in this range are not routed, this is not a requirement.
The list for the "Number of Addresses" In the IPv4 address block table was wrong for the 224.0.0.0/4 and 240.0.0.0/4 address spaces. The table stated that there were 268,435,455 addresses. 2 32 is indeed 265,435,455 but you have to add in the extra "0" address making the correct number of addresses 268,435,456.
