一个MAC如何控制isc-dhcp中的多个IP?

目前我在/etc/dhcp/dhcpd.conf为每个IP设置了这个configuration

 host 4 {hardware ethernet 02:00:00:50:f0:73;fixed-address 5.xxx.xxx.xxx;option subnet-mask 255.255.255.255;option routers 145.239.xxx.xxx;} 

我将如何设置MAC 02:00:00:73:ca:4b分配给1.1.1.1,2.2.2.2和3.3.3.3?

我的完整configuration文件是

 ddns-update-style none; default-lease-time 600; max-lease-time 7200; log-facility local7; option rfc3442-classless-static-routes code 121 = array of integer 8; option ms-classless-static-routes code 249 = array of integer 8; subnet 0.0.0.0 netmask 0.0.0.0 { authoritative; default-lease-time 21600000; max-lease-time 432000000; option routers 145.239.xxx.xxx; option domain-name-servers 8.8.8.8,4.2.2.1; option rfc3442-classless-static-routes 32, 145.239, xxx, xxx, 0, 0, 0, 0, 0, 145.239, xxx, xxx; option ms-classless-static-routes 32, 145.239, xxx, xxx, 0, 0, 0, 0, 0, 145.239, xxx, xxx; #ProxmoxIPv4 host 1 {hardware ethernet 02:00:00:f6:70:3e;fixed-address 178.xxx.xxx.xxx;option subnet-mask 255.255.255.255;option routers 145.239.xxx.xxx;} host 2 {hardware ethernet 02:00:00:e8:15:d5;fixed-address 178.xxx.xxx.xxx;option subnet-mask 255.255.255.255;option routers 145.239.xxx.xxx;} host 3 {hardware ethernet 02:00:00:43:1f:c9;fixed-address 178.xxx.xxx.xxx;option subnet-mask 255.255.255.255;option routers 145.239.xxx.xxx;} host 4 {hardware ethernet 02:00:00:50:f0:73;fixed-address 5.xxx.xxx.xxx;option subnet-mask 255.255.255.255;option routers 145.239.xxx.xxx;} host 5 {hardware ethernet 02:00:00:ed:e5:77;fixed-address 37.xxx.xxx.xxx;option subnet-mask 255.255.255.255;option routers 145.239.xxx.xxx;} host 6 {hardware ethernet 02:00:00:7f:7b:a8;fixed-address 37.xxx.xxx.xxx;option subnet-mask 255.255.255.255;option routers 145.239.xxx.xxx;} host 7 {hardware ethernet 02:00:00:8a:2b:79;fixed-address 37.xxx.xxx.xxx;option subnet-mask 255.255.255.255;option routers 145.239.xxx.xxx;} host 8 {hardware ethernet 02:00:00:4d:8b:01;fixed-address 46.xxx.xxx.xxx;option subnet-mask 255.255.255.255;option routers 145.239.xxx.xxx;} } 

如果可能的话,我想保持一行上的configuration
