Let me try to understand the traffic flow for the Internet. <br />
My PC can do ipv4 and ipv6. I created a tunnel with tunnelbroker.net. When I visit an ipv4 website, it will use the IPv4 stack, then send the GET request out through my firewall. Now, if I visit an IPv6 website, it will use the ipv6 stack. So, how will this work? how does the association between the IPv6 address and the IPv4 address happen? How does the PC know to send interesting traffic to tunnelbroker.net? Thanks

Can the experts educate me on how the ipv6 tunnel works, like tunnelbroker.net? I am a bit confused about the ipv6 tunnel and the actual vpn tunnel. It is not a vpn tunnel, isn't it?<br />
What does it mean by setting up a tunnel?<br />

Thanks

The Internet Protocol (IP) is the principal communications protocol in the Internet protocol suite for relaying datagrams across network boundaries, organized in abstraction layers, traditionally called "Link," "Internet," "Transport" and "Application”. Its routing function enables internetworking, and essentially establishes the Internet. IP defines packet structures that encapsulate the data to be delivered. It also defines addressing methods that are used to label the datagram with source and destination information.

A web server refers to the software that helps to deliver web content that can be accessed either through the Internet or through an intranet. The primary function of a web server is to store, process and deliver web pages to clients. The communication between client and server takes place using the Hypertext Transfer Protocol (HTTP). The most common use of web servers is to host websites, but there are other uses such as gaming, data storage, running enterprise applications, handling email, FTP, etc.

Network analysis is the process of identifying and remediating the processes and systems within a network, including performance, connectivity and security. The process is performed through the use of tools developed for monitoring and analyzing network activity. Network problems that involve finding an optimal way of doing something are studied under the name combinatorial optimization. Examples include network flow, shortest path problem, transport problem, transshipment problem, location problem, matching problem, assignment problem, packing problem, routing problem, Critical Path Analysis and PERT (Program Evaluation & Review Technique).
