<p>Can anyone shed some light on the following problem we are encountering?<br>
<br>
Multiple IP Addresses for a single MAC address<br>
<br>
We are using PXE to reimage a number of PC's(as many as 30-50<br>
at a time) and are supplying the PXE boot server address and filename <br>
using ISCDHCP. As each PC is booting, an address is issued based on<br>
a discover sent from the NIC initialization and then a second address<br>
is issued based on a discover sent sometime during the initialization <br>
of the image.<br>
Frequently while doing ths since there are two addresses being<br>
consumed by each PC, so many IP addresses are used that we <br>
run out of address and of course other PC's which may have been powered<br>
off and now are begin powered up are unable to get an address issued.<br>
<br>
ISCDHCP Version: 3.1.0<br>
OS Version: Solaris 10 11/06 s10s_u3wos_10 SPARC<br>
<br>
Also attached are the dhcpd.leases file and the output of dhcpd -d.<br>
