According to Microsoft:
How to use automatic TCP/IP addressing without a DHCP server
"A Windows-based computer that is configured to use DHCP can automatically assign itself an internet Protocol (IP) address if a DHCP server is not available. For example, this could occur on a network without a DHCP server, or on a network if a DHCP server is temporarily down for maintenance."

What IP addresses might have been assigned by APIPA?
169.180.23.5
What class License do APIPA addresses use?
APIPA addresses are in the range 169.254.0.1 through 169.254.255.254. These would be in the Class B address range.
Is all class B addresses are APIPA addresses?
No, not all Class B addresses are APIPA addresses. APIPA (Automatic Private IP Addressing) specifically refers to the range of IP addresses from 169.254.0.1 to 169.254.255.254, which is used for automatic private addressing when a device cannot obtain an IP address from a DHCP server. Class B addresses encompass a broader range from 128.0.0.0 to 191.255.255.255, which includes both public and private addresses, but only a small subset of APIPA addresses.
If no dhcp server is available on a network what type of configuration must computers on the network use for assignments of IP addresses?
Usually the systems will be assigned an APIPA address in the range 169.254.x.y in order to use resources in their own LAN. The APIPA configuration can also default to static IP addresses if necessary. If APIPA is not being used then the only way to use the network is to manually assign a static IP address and all of the required settings.
Assign the computers network adapter an IP address from a predefined pool of addresses 169.254.0.0 through169.255.255 that IANA Internet assigned numbers authority has reserved for this purpose.?
APIPA
True or False If your network does not need or use APIPA it must be uninstalled to avoid conflicts?
FalseEven if your network does not need or use APIPA, leaving it enabled is not necessarily problematic, because APIPA is designed to first check for the presence of a DHCP server and allow the DHCP server to assign addresses. In addition if a computers IP address has been assigned statically, APIPA does not reassign a new address. It only works with clients configured to use DHCP. APIPA can be disabled ,However, by editing the Windows operating system registry.
How do you find an APIPA address at first glance?
APIPA - Automatic Private IP Addressing uses a range of addresses 169.254.0.0-169.254.255.255 with a subnet mask of 255.255.0.0. If your address starts with 169.254, there is a good chance you are using APIPA.
What bit addresses are assigned to P0?
Addresses 80 - 87H are assigned to the P0 port
What are IP addresses that are not assigned from an available pool of IP addresses?
They are static.
How are URLs assigned to IP addresses?
URLs are assigned randomly to differently IP addresses. IP addresses are the numbers that identify a person's location online; it gives the general location and device.
Why the all zeros and all ones addresses are usually not assigned as host IP addresses?
These addresses are not assigned to devices because they have a reserved meaning. All zeroes refers to "this network", and all ones usually is assigned to a broadcast address (all devices).
What range does APIPA come from?
APIPA, or Automatic Private IP Addressing, is a feature used in networking that automatically assigns IP addresses in the range of 169.254.0.1 to 169.254.255.254. This range is reserved for devices that cannot obtain an IP address from a DHCP server. When a device is configured to use DHCP and fails to receive an address, it will assign itself an APIPA address within this range, allowing for local communication on the same network segment.
