Question

"IP Basic Concepts"  

1--Suppose that you work for a company that has been using IPv4 in each of its networks. After hearing a discussion about the differences between IPv4 and IPv6, your boss comes to you for advice on whether or not the company should upgrade each of its networks to IPv6. Suggest whether or not your boss should upgrade each network to IPv6. Provide at least two (2) reasons for your suggestion.

2--Suppose you work for a small company that has three (3) routers in its network design. Determine whether you would use static or dynamic routing to connect the routers. Justify your response with the key benefits that your choice provides.

Explanation / Answer

The Internet Protocol Version 4 (IPv4) is a protocol for use on packet-switched Link Layer networks e.g Ethernet. It's addressing capability is approximately 4.3 billion compared to IPv6 which has infinite number of addresses. Therefore, my boss should upgrade each network to IPv6 because IPv6 is more advanced and has better features compared to IPv4. IPv6 has the capacity to provide an infite number of adresses as stated above ; it is replacing IPv4 to accomodate the growing number of networks worldwide and help solve the IP address exhastion problem.

One difference between IPv4 and IPv6 is the appearence of the IPaddresses. IPv4uses uses four 1 byte decimal number, separated by a dot (i.e 192.168.1.1), while IPv6 uses hexadecimal numbers that are separated by colons (i.e fe::d4a8:6435:d2d8:d9f3b11).
