Hi Simon,
I changed config by your suggestion ( hosts definition in global scope ).
The problem is still here:
Oct? 4 09:01:02 dhcpserver dhcpd[9794]: DHCPDISCOVER from
10:27:be:12:08:a7 via 10.64.160.1: unknown client
Do you have some idea please?
Thanks in advance
Milan
Now my config is:
# option definitions common to all supported networks...
option domain-name "tes-media.sk";
option domain-name-servers 178.18.67.3, 178.18.67.1;
allow bootp;
default-lease-time 600;
max-lease-time 600;
allow unknown-clients;
# If this DHCP server is the official DHCP server for the local
# network, the authoritative directive should be uncommented.
authoritative;
# Use this to send dhcp log messages to a different log file (you also
# have to hack syslog.conf to complete the redirection).
log-facility local7;
# No service will be given on this subnet, but declaring it helps the
# DHCP server to understand the network topology.
# default
subnet 46.151.63.224 netmask 255.255.255.240 {}

I think I found the problem.
There can not be defined range in subnet which is for static clients.
I will test it more deeply and will give results.
In any case, thanks a lot for ideas.
