how do I make the zeroconf go away

The little Buffalo ADSL-router-box has a DHCP server, which is set to hand out particular fixed IP addresses to the MAC addresses of my computers; I have /etc/hosts files on all the machines saying things like '172.26.200.43 cow'. For the 8.04 machines, this works fine.
For the 9.04 machines, the address assignment is ignored entirely. However, something (which I think is zeroconf) talks to the ADSL-router-box and causes it to set things up in its DNS, meaning that I can say 'ssh node2@cow.local' and get to the machine called cow, whose IP address is however not 172.26.200.43 (and indeed changes every 24 hours).
How do I go about turning this off, so that the computers keep the addresses that I have assigned for them in the DHCP server on the router-box rather than daily going through some complicated protocol to negotiate a wrong address that keeps changing ?
Extracts from /var/log/syslog that might be relevant are at http://pastebin.com/T0rLdrc1
