Can the B receive the packet? If not why and provide solution to the problem? sharifah1 https://padlet.com/sharifah1/mket1313_271116/wish/139997284 Using IPv6 fragmentation are done at the end system. The end system need to know the smallest MTU in the path the data will be sent. Then the data will be fragment with the smallest MTU.]]> 2016-11-27 03:17:31 UTC https://padlet.com/sharifah1/mket1313_271116/wish/139997284 IPv6-Q3) Sketch an IPv6 packet with Extension header, containing TCP segment. Includes also all types of extension header sharifah1 https://padlet.com/sharifah1/mket1313_271116/wish/139997287 2016-11-27 03:17:39 UTC https://padlet.com/sharifah1/mket1313_271116/wish/139997287 IPv6-Q4) Why do we need to up grade IPv4 to IPv6. In your opinion does IPv6 making thing better or worst. Discuss. sharifah1 https://padlet.com/sharifah1/mket1313_271116/wish/139997307 Better:
-IPv6 provide the substantially larger Ip address than Ipv4.
-Redundancy of the unused timestamp is a waste of bandwidth
-Better handle congestion and router discovery, i.e Fragmentation is done at the source.
-Support for resource allocation.
Worst:
-The header is bigger.
-Latency and packet drop

-network complexity in terms of maintainance
-costly
-isolation of network from the global internet

To  provide a certain IP address to be public and a certain address to be private. So the private address can be access via a login page or a NAT.
Scenario 2:
An example of a scenario between two intranet via an internet. Access are only allow via VPN. NAT will be need to translate the IP address at the gateway of the intranet.
Scenario 3: 
DNS is a server that translate IP address to URL however if the DNS sits behind the NAT, access cannot be done. A mechanism of integration of NAT with DNS need to be done if the URL sits behind NAT.]]> 2016-11-27 04:10:56 UTC https://padlet.com/sharifah1/mket1313_271116/wish/139998290 NA Q1) Sketch the Private and hybrid Network in achieving privacy in network. sharifah1 https://padlet.com/sharifah1/mket1313_271116/wish/139998305 2016-11-27 04:11:23 UTC https://padlet.com/sharifah1/mket1313_271116/wish/139998305
