It's called APIPA (automatic private ip addressing).
If both DHCP server and DHCP client are properly configured, this is true.
A DHCP client will receive an Automatic Private IP Addressing (APIPA) address when it fails to obtain an IP address from a DHCP server after several attempts. This typically happens when there is no DHCP server available on the network or if the server is unreachable. APIPA assigns an IP address in the 169.254.0.1 to 169.254.255.254 range, allowing for local communication on the same subnet.

Nothing. That is not a valid IP address as its stands however ip addresses with the first 2 octets of 169.254.xxx.xxx means that Automatic Private IP Addressing has been enabled because no DHCP server was found and no static address has been defined.
169.254.10.1 is an IP address generated automatically by a computer when it is unable to lease an address from a DHCP server. It is called an Automatic Private IP Addressing (APIPA) address.
DHCP should only be enabled if your network is set up for dynamic IP addressing.
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."For more information, see Related Links, below.
DHCP
This is an APIPA (Automatic Private IP Addressing) address. When Windows computers can't get an IP address from a DHCP server, they automatically assign themselves this address.
When a Windows computer is configured to use DHCP and no DHCP server is available, it automatically assigns itself an Automatic Private IP Addressing (APIPA) address. This address falls within the range of 169.254.0.1 to 169.254.255.254. The computer uses this address to communicate with other devices on the same local network segment, but it cannot connect to external networks without a valid DHCP lease.
