Hi Jamie, thank you for responding. I have copied from the terminal 4
leases from the /var/lib/dhcp/dhcpd.leases file -- the first 2 leases
(159.218.146.157 and 159.218.147.8) were taken from non-contiguous sections
of the lease file and are visible when in Webmin I click on the
159.218.144.0 network and then click the List leases button. The next 2
leases (159.218.43.117 and 159.218.42.219) were copied from the same
dhcpd.leases file and are not visible in the Webmin lease listing. Below
that I have copied the appropriate sections from the /etc/dhcp/dhcpd.conf
file. I can not say exactly when this problem made itself known or what
change may have triggered it. Thank you for any direction you can give.
