Aws vpc : addressing cidr

•

1 like•1,023 views

The document discusses CIDR (Classless Inter-Domain Routing) notation, which is used to represent IP addresses and routing prefixes in a compact format. CIDR notation specifies the IP address followed by a slash and the routing prefix size. This allows the representation of both single IP addresses and entire networks. The number of addresses within a subnet is calculated using the prefix size, with larger prefixes encompassing more addresses. Examples are provided of common CIDR prefix sizes and their resulting subnet sizes and address ranges.

CIDR Notation is a compact representation of an IP
address and its own routing preﬁx. The notation is
build with the ip address and the routing preﬁx
equivalent to the number or leading 1-bits in the
routing preﬁx mask.
This notation is used either for IPv4 and IPv6. The IP is
followed by a slash character “/” and then the routing
preﬁx. The address may identify a single IP address or
the beginning of an entire network.

The number of addresses of a subnet deﬁned by the
preﬁx can be calculated as:
192.168.1.129/24 = 2^32-24 = 2^8 = 256 addr.
2 address size - preﬁx size
192.168.1.129/16 = 2^32-16 = 2^16 = 65536 addr.
192.168.1.129/8 = 2^32-8 = 2^24 = 16,777,216 addr.
192.168.1.129/32 = 2^32-32 = 2^0 = 1 addr.
