Flashcards

DHCP Server Configuration Errors

Issues with the DHCP server configuration that prevent a host from connecting to remote networks or the internet, even if the physical connection is working.

IP address binding to a client MAC address

DHCP servers link a unique IP address to each client device's MAC address, maintaining a client table to map these connections.

Client table verification

Comparing the IP configuration of a client device with the entries in the DHCP server's client table to identify configuration mismatches.

IP address release and renewal

A troubleshooting step to resolve IP configuration conflicts by releasing the current IP address and obtaining a new one from the DHCP server.
