Question

APIPA addresses are valid only for communications within a network segment that a given host is connected to. A host with APIPA-assigned address (i.e. an IP address in the range between and ) cannot connect to the Internet. The assignment of APIPA address typically indicates a problem related to:

a. SNMP (Simple Network Management Protocol)
b. DNS (Domain Name Server/Service)
c. SMTP (Simple Mail Transfer Protocol)
d. DHCP (Dynamic Host Configuration Protocol)

Answer 1

APIPA addresses are only valid for communication within a network segment that a host is connected to. If a device is assigned an APIPA address, it typically indicates a problem with the DHCP (Dynamic Host Configuration Protocol) server.

Step-by-step explanation:

APIPA addresses, also known as Automatic Private IP Addressing, are assigned to devices on a network when they cannot obtain an IP address from a DHCP server. These addresses are only valid for communication within the network segment that the device is connected to. The range for APIPA addresses is 169.254.0.1 to 169.254.255.254, with 169.254.0.0 and 169.254.255.255 being reserved.

A device with an APIPA-assigned address cannot connect to the Internet because APIPA addresses are not routable over the Internet. Instead, they are used for local network communication. If a device is assigned an APIPA address, it typically indicates a problem with the DHCP server. The DHCP server is responsible for assigning IP addresses to devices on a network. If it is not functioning properly or not available, devices resort to APIPA addresses as a fallback.

In this particular scenario, the problem related to the assignment of an APIPA address is most likely associated with the DHCP (Dynamic Host Configuration Protocol). The DHCP server is not assigning an IP address to the device, forcing it to use an APIPA address for communication.
