What will happen if a private IP address is assigned to a public interface connected to an ISP?
Click on the arrows to vote for the correct answerA. B. C. D. E.
If a private IP address is assigned to a public interface connected to an ISP, it will cause problems as private IP addresses are meant to be used within private networks and not on the public internet. Here are the possible outcomes:
A. Addresses in a private range will be not routed on the Internet backbone.
This is true. The internet backbone routers are programmed to drop packets with private IP addresses because they are not routable on the internet.
B. Only the ISP router will have the capability to access the public network.
This is false. If a private IP address is assigned to a public interface, the router will not be able to access the public network. Moreover, the router will not be able to route traffic to the internet.
C. The NAT process will be used to translate this address in a valid IP address.
This is a possible solution. Network Address Translation (NAT) is a process that translates private IP addresses into public IP addresses. If NAT is implemented, the private IP address can be translated to a valid public IP address before being sent out to the internet.
D. Several automated methods will be necessary on the private network.
This is false. Assigning a private IP address to a public interface will not require any additional automated methods on the private network. However, if NAT is used to translate private IP addresses to public IP addresses, then some configuration may be required.
E. A conflict of IP addresses happens because other public routers can use the same range.
This is possible. If a private IP address is assigned to a public interface, it may conflict with other public routers that are using the same private IP address range. This can cause routing issues and connectivity problems.
