IPv6 Network Connectivity tutorials

  • IPv4 uses 32 Bits (four Byte) addresses and it could address Approximately 4 Billion Addresses.

  • IPv4 Address exhaustion occurred on 3rd February 2011.

  • This limitation of IPv4 leads to development of IPv6.

  • IPv6 is the latest revision of Internet Protocol, that routes traffic across the internet.

  • IPv6 was developed by the IETF (Internet Engineering Task Force to deal with long-anticipated problem of IPv4 Address Exhaustion.

  • IPv6 uses a 128 Bit Addresses, allowing for 2^128 addresses.

  • Approximately 2128 numbers of addresses can be assigned i.e. roughly goes to 3.4*10^38. i.e. 340,282,366,920,938,463,463,374,607,431,768,211,456.

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

  • 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

  • Remember that :: Double Column may only be used once, so 22ad:54::5bd:4f:bc38:8d20 is valid but

  • 22ad:54::5bd:4f::8d20 is invalid.

  • IPv6 is designed to solve many of the problems such as Address depletion, security, auto configuration and extensibility.

  • Windows 7 is Duel Stack that is it supports both IPv4 and IPv6.

  • DirectAccess require IPv6. DirectAccess enable remote users to access the corporation network anytime they have Internet connection.

  • Remote Desktop uses IPv6. IPv6 also support File Sharing Security and Remote Access.

 

IPv6 ADDRESS TYPES

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.
