Only thing is, it must have been asking my ISP's DNS servers, and ended up getting an odd amalgam of the local internal IP address and my ISP's domain, eg: 192-168-1-5.tpgi.com.au This was a similar format to the external hostname given to my router by the ISP, which is in the form of 123-456-78-90.tpgi.com.au (where 123-456-78-90 represents an imaginary IP address 123.456.78.90). Here's what /var/log/system/log showed: Feb 24 05:03:42 192-168-1-5 kernel[0]: sleep Feb 24 05:03:42 pippin kernel[0]: Wake reason = USB1 Feb 24 05:03:42 pippin kernel[0]: System Wake Feb 24 05:03:43 pippin kernel[0]: USB (UHCI):Port 2 on bus 0x1d has remote wakeup from some device Feb 24 05:03:42 pippin configd[34]: setting hostname to "pippin.local" Feb 24 05:03:45 pippin kernel[0]: AirPort: Link Up on en1 Feb 24 05:03:47 192-168-1-5 configd[34]: setting hostname to "192-168-1-5.tpgi.com.au" Feb 24 05:03:47 192-168-1-5 mDNSResponder[22]: NOTE: Wide-Area Service Discovery \ disabled to avoid crashing defective DNS relay 192.168.1.1:53 Feb 24 05:03:49 192-168-1-5 mDNSResponder[22]: Note: Frequent transitions for \ interface en1 (192.168.1.5); network traffic reduction measures in effect Feb 24 05:03:51 192-168-1-5 Mail[215]: Type selection took over 1.000 seconds. Stopping early....(some line-wrapping added by me) Obviously, as far as problems go, this was a very minor one. But odd, too -- it really shouldn't have been trying to get a hostname off my ISP, given that the network is behind a NAT firewalled router/"modem". Also, this address was a figment of the computer's imagination: attempting to ping it from within the network failed. There were a number of suggestions as to how you could force Mac OS X to use a static hostname, but most of these seem to come with a warning as to why you shouldn't do that. In the end, since I am, err, "network administrator" of my home network I just gave myself a static IP address on the router, and told it to give that IP address the hostname I wanted. This seemed to work: Feb 25 00:04:04 192-168-1-5 kernel[0]: AirPort: Link Down on en1 Feb 25 00:04:07 pippin configd[34]: setting hostname to "pippin.local" Feb 25 00:04:21 pippin airportd[3594]: Error: Power unexpectedly off, bailing - Apple80211GetPower() = off (0) Feb 25 00:04:21 pippin airportd[3594]: Could not find any preferred networks; trying broadcast requests..
