Before 2001, the in-addr.arpa zones for the private networks [1] were delegated to a single instance of name servers, blackhole-1.iana.org and blackhole-2.iana.org, called the blackhole servers. The IANA -run servers were under increasing load from improperly-configured NAT networks, leaking out reverse DNS queries, also causing unnecessary ...
The original list of IPv4 address blocks was published in September 1981. [3] In previous versions of the document, [19] [20] network numbers were 8-bit numbers rather than the 32-bit numbers used in IPv4. At that time, three networks were added that were not listed earlier: 42.rrr.rrr.rrr, 43.rrr.rrr.rrr, and 44.rrr.rrr.rrr.

In Internet networking, a private network is a computer network that uses a private address space of IP addresses. These addresses are commonly used for local area networks (LANs) in residential, office, and enterprise environments. Both the IPv4 and the IPv6 specifications define private IP address ranges. [1] [2]
Today, such private networks are widely used and typically connect to the Internet with network address translation (NAT), when needed. Three non-overlapping ranges of IPv4 addresses for private networks are reserved. [8] These addresses are not routed on the Internet and thus their use need not be coordinated with an IP address registry.
The Internet Engineering Task Force (IETF) has reserved the IPv4 address block 169.254.0.0 / 16 (169.254.0.0 – 169.254.255.255) for link-local addressing. [1] The entire range may be used for this purpose, except for the first 256 and last 256 addresses (169.254.0.0 / 24 and 169.254.255.0 / 24), which are reserved for future use and must not be selected by a host using this dynamic ...
PRIVATE WiFi assigns you an anonymous, untraceable IP address that hides your actual IP address and location. PRIVATE WiFi solves the inherent security problems of public WiFi hotspots by giving you the same encryption technology used by corporations, big banks and the government.
The reason is that routing will not work if the same address ranges are used on both the private and the public side of a customer’s network address translation (NAT) equipment. Normal packet flow can therefore be disrupted and the customer effectively cut off the Internet, unless the customer chooses another private address range that does ...
