Please Explain why it is the right answer:

How did NAT help resolve the shortage of IPV4 addresses after the increase in SOHO, Small Office Home Office, sites requiring connections to the Internet? Choose the best answer below:
a.   It provides a migration path to IPV6.
b.   It permits routing the private IPV4 subnet 10.0.0.0 over the Internet.
c.   NAT adds one more bit to the IP address, thus providing more IP addresses to use on the Internet.
d.   It allowed SOHO sites to appear as a single IP address, (and single device), to the Internet even though there may be many devices that use IP addresses on the LAN at the SOHO site.

Answer:B
It permits routing the private IPV4 subnet 10.0.0.0 over the Internet.


1)Device with a direct connection to internet needs a public IP address.
2)The limited avalability of public IPv4 addresses is one of the problem facing the IP internet and the temporary solution to reduce the demand is address reuse.
3)So NAT was developed to provide a method that enables unlimited number of organisations to reuse private IPV4 addresses that decrease the demand for new public IPv4 addresses.

Hope you understand..Thank you.
