By Edward Tetz . Private addressing and Automatic or Dyanmic addressing were developed in response to a dwindling number of available public addresses.To resolve the issue, in 1996, IANA and IETF came up with private addressing, which allows organizations to use a large address space internally on their network while using only a few public addresses, rather than using only public addresses.

There is a particular range specified for the Automatic Private IP Addressing (APIPA). It runs from 169.254.0.0 to 169.254.255.255. Another range begins from 192.168.0.0 to 192.168.255.255.

The answer is simple binary: IP_address AND network_mask EQUALS network_address. For example, Does IP address 10.1.2.3 belongs to network 10.0.0.0 with netmask 255.0.0.0? 10.1.2.3 & 255.0.0.0 is 10.0.0.0, so the answer is: yes it does.
Private IP Addresses¶. The network standard RFC 1918 defines reserved IPv4 subnets for use only in private networks (Table RFC 1918 Private IP Address Space). RFC 4193 defines Unique Local Addresses (ULA) for IPv6 (Table RFC 4193 Unique Local Address Space).In most environments, a private IP subnet from RFC 1918 is chosen and used on all internal network devices. IP address classes - Subnet Note: Class A addresses 127.0.0.0 to 127.255.255.255 cannot be used and is reserved for loopback and diagnostic functions.

19/05/2020 · The allocated IP address range ensures that subnet IP ranges and destinations for custom routes in your VPC network do not overlap with address ranges that the private services access connection uses. You can create an allocated IP range manually if you want to control the CIDR block, or you can have Google Cloud create one for you.
Private IP addresses can't communicate directly with a public IP address. This means if a device that has a private IP address is connected directly to the internet, and therefore becomes non-routable, the device will have no network connection until the address is translated into a working address through a NAT, or until the requests it sends are sent through a device that does have a valid
