I just checked the hostids on my 2 primary machines on the same local 
network.  They just seem to be encodings of the machine's IP addresses. 
  And since both are PC class machines, the addresses look to be 
syllable swapped (but not byte swapped).

192.168.6.94 and 192.168.6.106
a8c05e06     and a8c06a06

So, I have to ask, does the machine you tried it on have an IP address?
