You must install 125 computers for a new business that wants to run TCP/IP and have access to the Internet. The ISP in town will assign you only four public IP addresses, so you decide to assign the computers addresses in the range 172.16.1.1/16 through 172.16.1.125/16. What else must you do to allow these computers to access the Internet

Configure a NAT

Explanation:

NAT stands for network address translation. It is a process of converting or translating a local or private address to a public routable address. private ip version 4 addresses are not routable on the internet. The ranges of private addresses are;

   10.0.0.0 - 10.255.255.255

   172.16.0.0 - 172.31.255.255

   192.168.0.0 - 192.168.255.255

The exhaustion of the ipv4 address due to its limited addresses, brought about the use of NAT to maximize the available private and public addresses. With NAT, a network of over 125 computers can access the internet using few public address translation.
