I never know what to do with "yourdomain", could you explain ?
It can be anything. Flower / thenudiebar / whatever.
If You use lets say 192.168.0.120 and then thenudiebar instead of yourdomain when You will ping thenudiebar it will ping the IP mentioned above.
I use it as well for blocking certain page...
If anyone tries to visit those pages he gets error...
Btw - this method of hostnaming the pcs has a major flaw... all the machines have to have static IP in your network...
I use static IP - yes. If You use this method You have static IPs too... but sometimes people connect machines via DHCP - this method will fail then - as machines will have different IP each time.
