The following answers are incorrect: The first bit of the IP address would be set to zero. Is incorrect because, this would be a Class A network address. The first two bits of the IP address would be set to one, and the third bit set to zero. Is incorrect because, this would be a Class<br \/>\nC network address.<br \/>\nThe first three bits of the IP address would be set to one. Is incorrect because, this is a distractor. Class D &#038; E have the first three bits set to 1. Class D the 4th bit is 0 and for Class E the 4th bit to 1.
