/etc/dnsmasq.conf on the gateway which is also pushed as sole DNS server:
address=/wiki.inter-actief.utwente.nl/10.10.3.17
Switch:~ daenney$ host wiki.inter-actief.utwente.nl
wiki.inter-actief.utwente.nl has address 10.10.3.17
Switch:~ daenney$ ping wiki.inter-actief.utwente.nl
PING zwarejongens.vereniging.utwente.nl (130.89.55.65): 56 data bytes
It seems that the ‘host’ command uses libc which uses nss which uses ‘resolv.conf’ resulting in the use of DNS server ‘192.168.1.1′ on the host command but the ping command seems to get its DNS-servers from somewhere else.
So, did Apple just do something funky, alter libc somehow or what the flying f*ck?
Funny.. I run into the exact same problem
Actually, I found out what happens.
The culprit is the infamous OS X utility called dscacheutil, which, amongst other things, caches DNS entries.
The fix?
dscacheutil -flushcacheand try again.
