Madeline travels all day and all night around the United States and no matter where she goes, her IP address is always the same. What technology is this?
  1. Mobile Access Ports
  2. Mobile IP
  3. Mobile Roaming IP Operations
Explanation
Answer: C - Mobile IP technology allows a user to move from one network to another and still use the same IP address. It is an improvement upon the IP protocol because it allows a user to have a home IP address associated with his home network and care-of address. The care-of address changes as he moves from one network to the other. All traffic that is addressed to his home IP address is forwarded to his care-of address.
