<DIV style="font-family:Arial, sans-serif; font-size:10pt;"><DIV>I'm running 2.46 on Tomato serving up DNS and DHCP to a mix of PC's, NAS's and a Mac. Everything is working great but I'm puzzled by the behavior of the Mac client (10.5.6). Every 10-15 seconds the Mac performs a reverse DNS query on it's own address. As far as I can tell, DNSMASQ seems to reply correctly with the host name but then 15 seconds later it queries again. Not sure if this has to to with Bonjour or not. IPV6 is turned off on the Mac. Here's a copy of the parameters to DNSMASQ:</DIV>

<DIV>The Mac is configured as "iMac1" both in the DNS section of the advanced networking settings as well as in the sharing settings section. Again, everything seems to work but it would be great to understand this and fix this.</DIV>
