| The Internet is a complex system, which has intricate tangle, connection diversity,
self-organization, and cluster and hierarchical structures. It is of current general interest
to understand scale free properties of the Internet. Recently, several intriguing
power-law distributions were reported for connectivity (1), the number of links (2) and
web pages (3) in the World-Wide Web. These scale free properties are essential in order
that the network is resilient and robust to random errors, breakdowns, and attacks (4).
