If I understand you correctly you want only hosts that have a matching mac address to be given an address for a specific subnet (192.168.100.0/24). For that you can use the 'static' keyword: dhcp-range=192.168.100.2,static,12h In case it is not what you want dhcp-host should have the form: dhcp-range=192.168.100.2,192.168.100.253,12h dhcp-host=ab:cd:ef:gh:ij:kl,fix-ip-to-be-given-to-host Thanks. :) My man page for dnsmasq doesn't have a information about optional static mode for dhcp-range like on link http://www.thekelleys.org.uk/dnsmasq/docs/dnsmasq-man.html: "The optional keyword may be static which tells dnsmasq to enable DHCP for the network specified, but not to dynamically allocate IP addresses: only hosts which have static addresses given via dhcp-host or from /etc/ethers will be served. A static-only subnet with address all zeros may be used as a "catch-all" address to enable replies to all Information-request packets on a subnet which is provided with stateless DHCPv6, ie --dhcp-range=::,static" For example configuration: interface=eth2 dhcp-range=192.168.100.0,static dhcp-range=192.168.102.0,static dhcp-range=10.0.0.0,static dhcp-host=ab:cd:ef:gh:ij:kl,192.168.102.10 With this configuration pc with mac "ab:cd:ef:gh:ij:kl" get 192.168.102.10 and no other ip. Аnd any other pc with a different mac will not receive any ip from my dhcp-server. If you want "fix" address and "non-fix" address on the same subnet (192.168.100.0/24): dhcp-range=192.168.100.100,192.168.100.150,12h dhcp-host=ab:cd:ef:gh:ij:kl,192.168.100.90 The above line means that the host with the mac address 'ab:cd:ef:gh:ij:kl' will always get 192.168.100.90. Any other hosts will get an ip addres from 192.168.100.100 to 192.168.100.150 (50 addresses available). Normally you would use one subnet per interface: interface=eth2 interface=eth3 dhcp-range=192.168.100.100,192.168.100.150,12h dhcp-range=192.168.101.100,192.168.101.150,12h The subnet to be used is the one set on the interface. -- John Doe ___ Dnsmasq-discuss mailing list Dnsmasq-discuss@lists.thekelleys.org.uk http://lists.thekelleys.org.uk/mailman/listinfo/dnsmasq-discuss
