RE: No Place Left to Hide on Tomorrow's Net?

Perhaps operating systems should generate a new random MAC address on each
reboot.  Just a thought.

"The primary change from IPv4 to IPv6 is the length of network addresses.
IPv6 addresses are 128 bits long (as defined by RFC 2373 and RFC 2374),
whereas IPv4 addresses are 32 bits.

IPv6 addresses are typically composed of two logical parts: a 64-bit network
prefix, and a 64-bit host part, which is either automatically generated from
the interface's MAC address or assigned sequentially."

Does anyone know if IPv6 addresses still contain embedded MAC addresses?
This feature might be a bit of a problem......

Personally, I think IPv6 is a red herring, but interestingly enough, I've
never heard this spin before. :-)

Thomas Crampton writes in The International Herald Tribune:

Billed as the next generation of the Internet, a new technical standard
enthusiastically embraced by China will allow greater traceability of
Internet users, potentially endangering those expressing views counter to
the government's.

The standard, known as IPv6, solves technical problems faced by the Internet
around the world, but Internet freedom advocates outside China warn that the
internationally developed norm would also allow Beijing authorities - or any
government or company for that matter - to have a better idea of what
individuals are doing on the Internet.

"There is now anonymity for criminals on the Internet in China," said Hu
Qiheng, chair of the Internet Society of China, a public-private group
founded five years ago to promote the Internet in China. "With the China
Next Generation Internet project, we will give everyone a unique identity on
the Internet."
