IPv4 address exhaustion timeline. IPv4 address exhaustion is the depletion of the pool of unallocated IPv4 addresses. Because the original Internet architecture had fewer than 4.3 billion addresses available, depletion has been anticipated since the late 1980s when the Internet started experiencing dramatic growth.
A public IP address is a globally routable unicast IP address, meaning that the address is not an address reserved for use in private networks, such as those reserved by RFC 1918, or the various IPv6 address formats of local scope or site-local scope, for example for link-local addressing. Public IP addresses may be used for communication ...
On a PC running Windows 10: On the task bar, select WiFi or Ethernet > click on the network you’re currently connected to > select Properties > your IP address is listed next to “IPv4 address.”
Unix-like operating systems commonly implement IP address blocking using a TCP wrapper, configured by host access control files /etc/hosts.deny and /etc/hosts.allow.. Both companies and schools offering remote user access use Linux programs such as DenyHosts or Fail2ban for protection from unauthorized access while allowing permitted remote access.
The technique was initially used to bypass the need to assign a new address to every host when a network was moved, or when the upstream Internet service provider was replaced but could not route the network's address space. It has become a popular and essential tool in conserving global address space in the face of IPv4 address exhaustion.

Note that IPv6 addresses are almost never shared, even for large organizations, because network address translation is typically not used with IPv6. Although IPv6 addresses can be highly dynamic, possibly changing even more often than IPv4 addresses, a single user will generally use the same /64 range, and their IPv6 address is unlikely to be ...
