Vizsgára készülök. Kérdés:Amennyiben valamilyen hiba miatt nem érhető el a DHCP-szerver, a Windows-kliensek milyen IP címet fognak kapni? Válaszlehetőségek: 10.x.y.z 0.0.0.0 127.0.0.1 169.254.x.y

"If no DHCP server is currently available (either because the server is temporarily down or because none exists on the network), the computer selects an IP address from a range of addresses (from 169.254.0.0 - 169.254.255.255) reserved by the Internet Assigned Numbers Authority (IANA) for that purpose. The client uses Address Resolution Protocol (ARP) to ensure that the chosen address is not already being used by another network computer. Once the computer has assigned itself an IP address, it can communicate over TCP/IP with other computers on the LAN that are either configured for APIPA or are manually set to the correct address range and a subnet mask value of 255.255.0.0. APIPA is enabled by default, but can be disabled in some cases. DHCP messages notify the user when they are switched between DHCP addressing and APIPA."

Így már utána tudsz nézni részletesebben, ha szükséges.

169.254...

Gyakran láttam ezt a packet tracerben illetve virtualboxvan is.

De miért nem probálod ki magad? Jobban megtanulod.

2. A Wikipedia így értekezik erről:

"The Internet Engineering Task Force (IETF) has reserved the IPv4 address block 169.254.0.0/16 (169.254.0.0 – 169.254.255.255) for link-local addressing."
