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.
The all-zeroes address is reserved as the subnet-router anycast address. [18] The subnet router anycast address is the lowest address in the subnet, so it looks like the “network address”. If a router has multiple subnets on the same link, then it has multiple subnet router anycast addresses on that link. [19] The first and last address in ...
A subnet mask encodes the same information as a prefix length but predates the advent of CIDR. In CIDR notation, the prefix bits are always contiguous. Subnet masks were allowed by RFC 950 [6] to specify non-contiguous bits until RFC 4632 [5]: Section 5.1 stated that the mask must be left contiguous. Given this constraint, a subnet mask and ...
For example, the sample diagram does not indicate the physical type of connection between the PCs and the switch, but since a modern LAN is depicted, Ethernet may be assumed. If the same style of line was used in a WAN (wide area network) diagram, however, it may indicate a different type of connection.
Network diagram with IP network addresses indicated e.g. 192.168.100.3.. A network address is an identifier for a node or host on a telecommunications network.Network addresses are designed to be unique identifiers across the network, although some networks allow for local, private addresses, or locally administered addresses that may not be unique.

Broadcast address derivation example Network IP address breakdown for 172.16.0.0 / 12 Binary form Dot-decimal notation In bold below is shown the host part (suffix) of the IP address, with the network address prefix being the non-bold bits to its left. To obtain the broadcast address, the host bits get set to all 1's, while the network address ...
Anycast is a network addressing and routing methodology in which a single IP address is shared by devices (generally servers) in multiple locations. Routers direct packets addressed to this destination to the location nearest the sender, using their normal decision-making algorithms, typically the lowest number of BGP network hops.
Restricted to networks used by the organization administering the local network. (For example, these addresses might be used over VPNs; when packets for this group are routed over the public internet (where these addresses are not valid), they would have to be encapsulated in some other protocol.) ffxe::/16: 224.0.1.0-238.255.255.255: Global scope
