If I want to setup DHCP to allocate some address based on MAC address with the range I specified prevent that asssignmet?

ddns-update-style interim;
allow client-updates;

# if you have fixed-address entries you want
update-static-leases on;

key dhcpupdate {
algorithm hmac-md5;
secret mysecretkey==;
}

zone tse.boeing.com {
primary 10.46.70.2;
key dhcpupdate ;
}

zone 70.46.10.in-addr.arpa {
primary 10.46.70.2;
key dhcpupdate ;
}

subnet 10.46.70.0 netmask 255.255.255.0 {

option routers 10.46.70.1;
option subnet-mask 255.255.255.0;

option domain-name "tse.boeing.com";
option domain-name-servers 10.46.70.2;

option time-offset -5; # Eastern Standard Time
option ntp-servers 10.46.70.6;
default-lease-time 259200;
max-lease-time 259200;


group {
option domain-name "tse.boeing.com";
ddns-domainname "tse.boeing.com";

host tm-stnd {
hardware ethernet 00:A0:69:0B:AF:A2;
fixed-address 10.46.70.6;
option host-name "tm-stnd";
ddns-hostname "tm-stnd";
}
}

range 10.46.70.15 10.46.70.49;

No , it will not prevent.
host tm-stnd will get ip address as 10.46.70.6
