[Dnsmasq-discuss] Ping does not work but nslookup works (Use dnsmasq on Mac OS X)

When I run "dig oxygen.yulab", I see the following log.

Dec 23 10:05:35 dnsmasq[51588]: query[A] oxygen.yulab from 127.0.0.1
Dec 23 10:05:35 dnsmasq[51588]: forwarded oxygen.yulab to 192.168.1.25
Dec 23 10:05:35 dnsmasq[51588]: reply oxygen.yulab is 192.168.1.163

When I run "dig @192.168.1.25 oxygen.yulab", I see the following log.

Dec 23 10:07:24 dnsmasq[51588]: query[A] oxygen.yulab from 127.0.0.1
Dec 23 10:07:24 dnsmasq[51588]: cached oxygen.yulab is 192.168.1.163

So this means dnsmasq is running correctly? Does mac's ping use
something else to resolve ip addresses? Thanks.
