The IPv6 protocol stack also includes duplicate address detection to avoid conflicts with other hosts. In IPv4, the method is called link-local address autoconfiguration. [1] However, Microsoft refers to this as Automatic Private IP Addressing (APIPA) [3] or Internet Protocol Automatic Configuration (IPAC).
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 ...
A special case of private link-local addresses is the loopback interface. These addresses are private and link-local by definition since packets never leave the host device. IPv4 reserves the entire class A address block 127.0.0.0 / 8 for use as private loopback addresses. IPv6 reserves the single address ::1.
They are PTR queries for subdomains of in-addr.arpa (for IPv4 addresses) [3] and ip6.arpa (for IPv6 addresses). [4] For example, to find the domain name associated with the IP address 203.0.113.22, one would send a PTR query for 22.133.0.203.in-addr.arpa. Misconfigured hosts [5] often send reverse DNS queries for private addresses to the public ...
Carrier-grade NAT. Carrier-grade NAT (CGN or CGNAT), also known as large-scale NAT (LSN), is a type of network address translation (NAT) used by ISPs in IPv4 network design. With CGNAT, end sites, in particular residential networks, are configured with private network addresses that are translated to public IPv4 addresses by middlebox network address translator devices embedded in the network ...
In IPv6 global addresses are used end-to-end, so even home networks may need to distribute public, routable IP addresses to hosts. Since it would not be practical to manually provision networks at scale, in IPv6 networking, DHCPv6 prefix delegation ( RFC 3633 ; RFC 8415 § 6.3) is used to assign a network address prefix and automate ...
