Every year‚ almost 7 billion tons of carbon dioxide is released into the atmosphere by human activity (“How do we contribute individually to global warming.” Global Warming: 2006. Web.12 Oct. 2011). That is the equivalent of 107‚700‚000 jet airplanes being in the air at once! This harrowing figure is the main cause of global warming‚ and has been increasing for the last 50 years. Global warming is caused by the increase of greenhouse gases‚ carbon dioxide and methane primarily‚ in the earth ’s upper

Background Arkko and Townsley in (2011) indicated that IP (internet protocol) is a standardized set of communication mechanisms used to establish connections amongst devices over the internet by exchanging packet datagrams developed over the past 40 years by DARPA (Defence Advanced Research Projects Agency) in US. Moreover‚ IP enables every single devices to communicate with each other by assigning unique numbers to them which is called IP addresses. The internet IP address is governed by IANA (Internet
