Section: Addressing and Routing Protocols in an Existing Network Explanation Explanation:
The IP address 169.254.173.233 is an example of an Automatic Private IP Addressing (APIPA) address.
On networks that utilize IP, each computer requires a unique IP address in order to access network resources. If an APIPA-capable computer, which must be running Windows 2000 or later, is configured to use Dynamic Host Configuration Protocol (DHCP) and is unable to obtain an IP address from a DHCP server, it will assign itself an APIPA address. An APIPA IP address is in the range of 169.254.0.0 to
169.254.255.255.
The computer with this address will most likely not be able to access other computers on the network unless those computers are also using APIPA addresses. A computer that has an APIPA address continually checks the network for a DHCP server. When a DHCP server becomes available, the computer releases its APIPA address and leases an IP address from the DHCP server.
IP version 4 (IPv4) addresses are 32bit (four-byte) addresses typically written in dotted-decimal format, where each byte is written as a decimal value from 0 to 255 and separated by dots. All IPv4 addresses fall into one of several classes. Class A IP addresses range from 1.0.0.0 through 126.255.255.255, Class B IP addresses range from 128.0.0.0 through 191.255.255.255, and Class C addresses range from 192.0.0.0 through 223.255.255.255. Two other classes of IP addresses exist: Class D and Class E.
Class D addresses are reserved for multicast use, and Class E addresses are reserved for experimental use.
Neither Class D addresses nor Class E addresses can be used on the Internet. The table below shows the classes of IPv4 addresses and their ranges:

IPv4 addresses can be either public or private. A public IP address is an address that has been assigned by the Internet Assigned Numbers Authority (IANA) for use on the Internet. IANA has also designated several ranges of IPv4 addresses for use on internal private networks that will not directly connect to the Internet.
The table below shows the IPv4 addresses that IANA designated for private use:
