Relation between IPv6 and IPv4 on Window 2008

Asked by: AXISHK

Is there any relation on converting IPv4 to IPv6 under Window 2008 ? Currently, the IPv6 address is fe80::2113:c350:8ca4:95f3%11 when I configure a IPv4 address with 192.168.150.41. However, Hex address of this address should be C0:A8:96:29. What is the relationship between these two addresses.

 Inaddition, what does symbol "%11" represent ?

Thanks.

There are no relations between IPv4 and IPv6 addresses.

 

by: JBlondPosted on 2009-11-05 at 00:40:59ID: 25747628

The "%11" is the interface indentifier

http://technet.microsoft.com/en-us/library/cc738446%28WS.10%29.aspx

On your server if you run

netsh interface ipv6 show interface

at the command prompt the interface with this IPv6 address should be interface 11

So, the IPv6 is randomly assigned, based on what ?

Thanks.

 

by: JBlondPosted on 2009-11-05 at 01:48:10ID: 25747924

It's based on the MAC address of the NIC.

See section 'Single subnet with link-local addresses' at http://technet.microsoft.com/en-us/library/cc738446%28WS.10%29.aspx

If you are in mood for reading: http://en.wikipedia.org/wiki/IPv6

(inserts)
fe80::/10  The link-local prefix specifies that the address is only valid on a single link. This is analogous to the autoconfiguration IP addresses 169.254.0.0/16 in IPv4.
The length of network addresses emphasize a most important change when moving from IPv4 to IPv6. IPv6 addresses are 128 bits long (as defined by RFC 4291), whereas IPv4 addresses are 32 bits; where the IPv4 address space contains roughly 4.3×109 (4.3 billion) addresses, IPv6 has enough room for 3.4×1038 unique addresses.

IPv6 addresses are typically composed of two logical parts: a 64-bit (sub-)network prefix, and a 64-bit host part, which is either automatically generated from the interface's MAC address or assigned sequentially.
Because the globally unique MAC addresses offer an opportunity to track user equipment, and so users, across time and IPv6 address changes, RFC 4941 was developed to reduce the prospect of user identity being permanently tied to an IPv6 address, thus restoring some of the possibilities of anonymity existing at IPv4. RFC 4941 specifies a mechanism by which time-varying random bit strings can be used as interface circuit identifiers, replacing unchanging and traceable MAC addresses.
