NO, that is NOT the hostname, and it is NOT neccessary to set it. In 
fact, unless you know what it is for, then I recommend against 
touching it.

Mac OS X will send the computer name by default, set it by opening 
System Preferences, Click on the Sharing icon, then set it in the box 
labelled Computer Name at the top. Be aware that whilst the Mac is 
happy with spaces etc in the name, it makes the dns a bit hard to use 
- so best to stick to dns-friendly character set (0-9, a-z, '-').
