What makes IP spoofing possible for computers on the Internet?
A) network address translation

C) the 32-bit address space
D) the DNS hierarchy

Question

Quizplus · Accepted Answer

IP spoofing is possible because there is a lack of authentication in the IP protocol. This means that a sender can insert a false source IP address in the header of an IP packet and the receiver will accept it as the legitimate address. Network address translation (A) and DNS hierarchy (D) are not directly related to IP spoofing. The 32-bit address space (C) might make it easier to guess or scan for valid IP addresses, but it is not a direct cause of IP spoofing.
