  2. IPv6 brokenness and DNS whitelisting - Wikipedia

    en.wikipedia.org/wiki/IPv6_brokenness_and_DNS...

    Other ISPs are sent only A records, thus preventing users from attempting to connect over IPv6 when hostnames are used instead of ipv6-addresses. Numerous concerns were raised about the practicality of DNS allowlisting as a long-term large-scale solution, such as scalability and maintenance issues relating to the maintenance of large numbers of ...

  3. IPv6 address - Wikipedia

    en.wikipedia.org/wiki/IPv6_address

    IPv6 addresses are assigned to organizations in much larger blocks as compared to IPv4 address assignments—the recommended allocation is a / 48 block which contains 2 80 addresses, being 2 48 or about 2.8 × 10 14 times larger than the entire IPv4 address space of 2 32 addresses and about 7.2 × 10 16 times larger than the / 8 blocks of IPv4 ...

    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 ...

    en.wikipedia.org/wiki/IP_address

    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 ...

    en.wikipedia.org/wiki/IPv4_address_exhaustion

    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.
