Zorluk: OrtaIP Addressing and Network Configuration

A network technician is reviewing host IP configuration symptoms across several workstations on a corporate subnet. Match each observed network diagnostic symptom on the left with its underlying configuration cause or mechanism on the right.

  • A workstation receives an IP address of 169.254.108.44 and cannot access internal local network shares or the internet.Automatic Private IP Addressing (APIPA) assignment triggered by DHCP unreachability
  • A host can ping local devices on the 192.168.10.0/24 subnet but fails to reach any hosts on external networks.Missing or misconfigured Default Gateway address
  • A computer can ping internet servers using their public IP address (such as 1.1.1.1) but fails to load web pages using domain names.Unreachable or misconfigured Domain Name System (DNS) server
  • A network printer dynamically receives the exact same IP address from the server every time its network adapter boots.DHCP reservation configured using the device MAC address

Cevap

169.254.x.x address correlates with APIPA assignment due to unreachable DHCP; local connectivity without external access correlates with a Default Gateway misconfiguration; successful IP ping with failed hostname resolution correlates with a DNS server misconfiguration; consistent dynamic IP assignment correlates with a DHCP reservation.
Each diagnostic symptom directly correlates with a fundamental networking role: APIPA (169.254.0.0/16) occurs when a client fails to receive a DHCP response; a default gateway routes traffic beyond the local subnet; DNS translates domain names to IP addresses; and a DHCP reservation dynamically assigns a specific IP to a fixed MAC address.

Adım Adım Çözüm

1
Analyze host IP address ranges and automatic fallback protocols
Identify 169.254.108.44 as a Link-Local (APIPA) IPv4 address generated when DHCP requests time out.
Windows hosts automatically assign an APIPA address when they cannot locate a DHCP server.
2
Examine routing requirements for inter-subnet communication
Correlate local network connectivity without external network access to the gateway router.
Hosts use the default gateway to forward packets destined for non-local IP networks.
3
Evaluate name resolution functions
Recognize that IP reachability with hostname failure indicates name resolution breakdown.
DNS resolves human-readable domain names to numerical IP addresses; failing DNS prevents domain resolution while raw IP routing remains functional.
4
Differentiate IP address assignment techniques
Identify MAC-based server rules as DHCP reservations.
DHCP reservations ensure host devices receive consistent IP settings via DHCP based on their hardware MAC address.
