  2. IPv6 - Wikipedia

    en.wikipedia.org/wiki/IPv6

    If IPv4 is still used in the local area network (LAN), however, and the ISP can only provide one public-facing IPv6 address, the IPv4 LAN addresses are translated into the public facing IPv6 address using NAT64, a network address translation (NAT) mechanism. Some ISPs cannot provide their customers with public-facing IPv4 and IPv6 addresses ...

  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 ...

  4. IP address - Wikipedia

    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 ...

  5. Unique local address - Wikipedia

    en.wikipedia.org/wiki/Unique_local_address

    A unique local address (ULA) is an Internet Protocol version 6 (IPv6) address in the address range fc00:: / 7. [1] These addresses are non-globally reachable [ 2 ] (routable only within the scope of private networks, but not the global IPv6 Internet).

  6. Reserved IP addresses - Wikipedia

    en.wikipedia.org/wiki/Reserved_IP_addresses

    Used for link-local addresses [5] between two hosts on a single link when no IP address is otherwise specified, such as would have normally been retrieved from a DHCP server 172.16.0.0/12 172.16.0.0–172.31.255.255

  7. Network address translation - Wikipedia

    en.wikipedia.org/wiki/Network_address_translation

    The public address (typically assigned by an Internet service provider) is used by the router for communicating with the rest of the Internet. As traffic passes from the network to the Internet, NAT translates the source address in each packet from a private address to the router's public address.

  8. IVI Translation - Wikipedia

    en.wikipedia.org/wiki/IVI_Translation

    Address translation defined in RFC 6052 [4] is a stateless mapping scheme, which embeds IPv4 address in network specific IPv6 prefix and forms IPv4-converted and IPv4-translatable addresses. The IPv4-converted IPv6 addresses are the IPv6 addresses used to represent IPv4 nodes in an IPv6 network.

  9. IPv6 deployment - Wikipedia

    en.wikipedia.org/wiki/IPv6_deployment

    It uses dual-stack PPPoE with one public static IPv4 address and /56 IPv6 prefix delegated via DHCP-PD. UPC Czech Republic have deployed IPv6 on residential DOCSIS lines since 2017. [ 111 ] IPv6-only network with IPv4 over DS-Lite is used.
