IPV6 [ Internet Protocol Version 6 ] tutorials

The problem with IPV4 was that it had reached potential exhaustion of IP address. Now a day 32 bits was not sufficient for an addressing structure.

  • IPV6 offers much larger address structure so that all organization could easily use unique grouping network of IP address.

  • IPV6 address is made up of 8 Groups of 4 HEX Characters (128 bits)

  • Approximately 2128 numbers of addresses can be assigned i.e. roughly goes to 3.4*1038. i.e. 340,282,366,920,938,463,463,374,607,431,768,211,456. Too large number to compare.

  • By above IPV6 implementation the scarcity of IP address will defiantly solve.

  • The IPV6 128 bit address is divided at 16 bit boundaries, and each 16 bit block is converted to a 4 digit hexadecimal number (0 to 9 and A to F).

  • IPv6 prefixes are expressed in the same way as IPv4 notation or Slash Notation for example 21bd:94:://64 is the subnet on which the address 21bcd:94::12ab:23bd:43dc:8c01 is located. In this example the first 64 bits are the NETWORK ADDRESS or NETWORK ID and rest 64 bits are for HOST ID.

  • Colons “:” are used as separators. This representation is called colon-hexadecimal.

  • Consider following IPv6 address

  • 22ad:0054:0000:0000:05bd:004f:bc38:8d20

Rule 1) Removing the leading zeros within each 16 bit block, however each block must

  • have at least a single digit.

  • 22ad:54:0:0:5bd:4f:bc38:8d20

Rule 2) Removing contiguous sequence of zeros can be compressed to ::

  • So previous address can be represented as

  • 22ad:54::5bd:4f:bc38:8d20



1) UNICAST :- Packets addressed to a unicast address are delivered to a single interface. RFC 2373 allows multiple interfaces to use the same address, provided that these interfaces appear as a single interface to the IPv6 implementation on the host. This kind of arrangement where multiple interfaces hold one address is used for LOAD BALANCING.


2) MULTICAST :- identifies multiple interfaces. Packets addressed to a multicast address are delivered to all interfaces that are identified by the address.


3) ANYCAST :- Identifies multiple interfaces. Packets addressed to an anycast address are delivered to the nearest interface identified by the address. The nearest interface is the closest in term of routing distance, or number of hops. An anycast address is used for one-to-one-of many communication with delivery to a single interface. It finds the nearest based on Router Cost.



IPv6 supports the following types of UNICAST Address






Used for Internet (V2)

  • The first three bits (Higher Level) are always 001

  • The next 13 bits known as TLA (Top Level Aggregator) are allocated by IANA (Internet Assigned Numbers Authority). IANA allocates the TLA to Local Internet Registries that in turn allocate individual TLAs to Large Internet Service Provider (ISP)

  • Next 8 bits are reserved for future expansion

  • Next 24 bits of the address contain the NLA (Next Level Aggregator). This identifies a specific customer site. The NLA enable an ISP to create multiple levels of addressing hierarchy within a network.

  • The next 16 bits contain SLA (Site Level Aggregator) which is used to organize addressing and routing for downstream ISP and to identify sites or subnets within a site.

  • The next 64 bits identify interface within subnet. This is the 64 bits Extended Unique Identifier (EUI-64) address. This EUI-64 address are assigned directly to network adaptor (NIC) cards or derived from the 48 bits MAC address of the network card.


Following is summarized format of IPv6 128 bits

3 bits

13 bits

8 bits

24 bits

16 bits

64 bits






NIC Interface ID




  • This is similar to IPv4 address that is auto-configured through APIPA.

  • In IPv4 APIPA assigned address from

  • In IPv6 you can identify Link-Local address by an FP of 1111 1110 10 which is followed by 54 zeros.

  • It always begins with FE80+54 bits 0 + 64 bits assigned to NIC card

  • Nodes use link-local address when communicating with neighboring nodes.

  • You have 64 bits for NETWORK i.e. 18,446,744,073,709,551,616 Networks

  • You have 64 bits for HOST i.e. again 18,446,744,073,709,551,616 Hosts

  • A link local address is required for ND (Neighbor Discovery) and is always automatically configured, even if no other unicast address is allocated.

  • To check Link-local go to RUN – CMD – ipconfig /all



  • Site-Local IPv6 addresses are equivalent to the IPv4 Private address.

  • For IPv4 we have (,,

  • Private Intranets that do not have a direct, Routed connection to the IPv6 section of the Internet can use SITE-LOCAL address without conflicting with aggregatable Global unicast address.

  • Site-Local Addresses begin with FEC0, followed by 32 zeros and then by a 16 bit subnet identifier that you can use to create subnets within your organization

Practice following command

1) Manually set IPv6 property of NIC card and assign IPv6 and DNS manually or

2) NETSH INTERFACE IPV6 SET ADDRESS “local area connection 1” f3c0:0:0:fffe::2

NETSH INTERFACE IPV6 ADD DNDSERVER “local area connection 1” fec0:0:0:fffe::1



3) on IPv4 to run – cmd – ping is same as on IPv6 run – cmd – ping ::1

4) you can also ping other such as run – cmd – ping fec0:0:0:fffe::1
