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 8 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.

 

IPv6 UNICAST ADDRESSES:-

  • IPv6 supports the following types of UNICAST Address

GLOBAL

LINK-LOCAL

SITE-LOCAL

 

1) GLOBAL IPv6 UNICAST ADDRESSES

  • 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

001

TLA ID

Reserved

NLA ID

SLA ID

NIC Interface ID

 

 

2) LINK LOCAL IPv6 UNICAST ADDRESS

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

  • In IPv4 APIPA assigned address from 169.254.0.0/16

  • 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

  •  

3) SITE LOCAL IPv6 UNICAST ADDRESS

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

  • For IPv4 we have (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16)

  • 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 aggregately 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

 

View and Configure IPv6 Address

  • Press Windows Logo Start Key or Point to the bottom left corner of the taskbar and click Start to get Start Screen.

  • Type ‘Control’ and then select Control Panel.

  • In control Panel Click Network and Internet

  • In Network and Internet panel , click View Network Status and Tasks.

  • This will open Network and Sharing Center, from the right hand side click Local Area Connection or click on your LAN card name.

  • This will open Local Area windows, Click on “Detail” Button. This will open new windows with all configuration detail of selected LAN card. You can verify IPv6 Address from there.

  • Click Close button.

  • To change IPv6 address, click on Properties button. it will open new windows.

  • Scroll down and select Internet Protocol Version 6 (TCP / IPv6) and click Properties button again.

  • It gives you two choice, Obtain an IP Address Automatically or Use the following IP Address.

  • If you want to configure IPv6 address manually, click on Radio button ¤ Use the following IPv6 address:

  • Now enter IP Address for example: f3c0:0:0:fffe::5

  • Enter Subnet Prefix Length as 64

  • Enter Default Gateway as f3c0:0:0:fffe::1

  • Once Done Click OK to close configuration window.

 

To configure IPv6 Address using Command Prompt do as follow.

  • Press Windows Logo Start Key or Point to the bottom left corner of the taskbar and click Start to get Start Screen.

  • Type CMD and then select CMD, Right Click and then choose Run As an Administrator

  • This will open Administrator: Command Prompt Window

  • Type NETSH command as follows

  • NETSH INTERFACE IPV6 SET ADDRESS “local area connection 1” f3c0:0:0:fffe::5

  • Confirm you new IPv6 address by applying IPCONFIG /ALL

  • NETSH INTERFACE IPV6 SHOW NEIGHBORS
