As this question is a bit longer I will separate it to three parts Most home networks use network address translation(NAT). This way several computers can be used on the network even though there is only one public IP-address. In the network below we have a public IP-address 88.125.168.121 and for the machines connected to the home network we have private IP-addresses that are connected to local network 192.168.0.0/16 a)When Client was connected to the NAT-router it received IP-address 192.168.7.15/16. How did that happen?

Router NAT-translation table \begin{tabular}{|c|c|} \hline Wide area network-side & Local area network-side \\ \hline 88.125.168.121:30300 & 192.168.7.15:23450 \\ \hline \end{tabular}
