Operating Systems Linux Debian Question on the dhcp-server configuration for a fixed IP address. Post 302393330 by Corona688 on Monday 8th of February 2010 12:28:14 PM

DHCP is sometimes frustratingly intelligent about assigning addresses. If said switch already has a lease -- or someone else already has a lease on that same address, or even if some random machine is misconfigured to use it -- that might take precedence over anything statically assigned. I think this is because there's no proactive way for a DHCP server to tell a client to go away and be something else. You might have to delete some leases and power cycle things.

NAME
dhclient.leases - DHCP client lease database DESCRIPTION
The Internet Systems Consortium DHCP client keeps a persistent database of leases that it has acquired that are still valid. The database is a free-form ASCII file containing one valid declaration per lease. If more than one declaration appears for a given lease, the last one in the file is used. The file is written as a log, so this is not an unusual occurrence. The format of the lease declarations is described in dhclient.conf(5). FILES
