Yeah, dhcpd rotates address assignments through the range, from
what I've seen.  If you want to nail up a specific IP every time,
make a special entry in /etc/dhcpd.conf like this:

host myhostname {
  hardware ethernet 00:10:a4:99:99:7b;
  fixed-address 192.168.0.10;
}

I don't know about the arpwatch thing.
