The Dynamic Host Configuration Protocol version 6 (DHCPv6) is a network protocol for configuring Internet Protocol version 6 (IPv6) hosts with IP addresses, IP prefixes and other configuration data required to operate in an IPv6 network. It is the IPv6 equivalent of the Dynamic Host Configuration Protocol for IPv4. IPv6 má nahradiť predchádzajúci štandard IPv4, ktorý so svojimi 32-bitovými adresami podporuje "iba" niečo viac ako 4 miliardy (2 32) adries. IPv6 používa pre svoje adresy širší rozsah 128 bitov a podporuje teda 2 128, alebo približne 3.4×10 38, teda 340 sextiliónov adries. Auto-configured IPv6 address is known as Link-Local address. This address always starts with FE80. The first 16 bits of link-local address is always set to 1111 1110 1000 0000 (FE80). The next 48-bits are set to 0, thus: Disable IPv6 operation on an interface when Duplicate Addess Detection (DAD) fails for a link-local address. By default, after a DAD fails, the duplicate address is not assigned to the interface but IPv6 continues to operate.

Internet Protocol version 6 (IPv6) IPv6 is short for "Internet Protocol version 6". IPv6 is the "next generation" protocol designed by the IETF to replace the current version of Internet_Protocol, IP Version 4 or IPv4.. IPv6 was initially designed with a compelling reason in mind: the need for more IP addresses. IPv6 static Addressing and DNSv6 | Network World 5) Click on “Use the following IPv6 address” and in the IPv6 Address field, type in the IP address you want to use (in my case, I typed in fda8:06c3:ce53:a890:0000:0000:0000:0002)

Address introduction An IPv4 address has 32 bits. An IPv6 address has 128 bits and looks a bit wild. Extending the address space from 32 bits to 128 bits was one of the driving reasons to develop IPv6. The IPv6 addressing architecture is defined in RFC 2373, which supersedes RFC 1884. An IPv6 address can be in one of three categories: Nov 07, 2017 · IPv6 addresses are assigned by RIRs to ISPs or organizations directly, then ISPs allocate addresses to customers, but all this location information may not necessarily be well-documented. If the IPv6 address is newly allocated and not entered into the geolocation databases, then that could cause problems. Parts of the IPv6 Address. An IPv6 address is 128 bits in length and consists of eight, 16-bit fields, with each field bounded by a colon. Each field must contain a hexadecimal number, in contrast to the dotted-decimal notation of IPv4 addresses. In the next figure, the x's represent hexadecimal numbers. Figure 3-2 Basic IPv6 Address Format IPv6 supports three address types: unicast, multicast, and anycast. Unicast IPv6 address allows a packet delivered to one interface. When it comes to the multicast IPv6 address, the packet is delivered to multiple interfaces. Anycast IPv6 address makes a package delivered to the nearest of multiple interfaces (in terms of routing distance). IPv6. The long term solution is to switch to Internet Protocol version 6 (IPv6). IPv6 has trillions of trillions of addresses, enough to give every computer in the world a unique IP address. Unfortunately, IPv6 is mostly incompatible with IPv4, and implementing it often requires replacing equipment such as routers.
