changes needed to be done once we change master to public ip

[varghese k renny]

   if i change my master system to dns like demo.sigmainfo.in:8050
Where all i needed to change in 
jenkins url: demo.sigmainfo.in:8050/jenkins
Advanced setting of slave : instead of HOST:PORT whether i needed to give 
demo.sigmainfo.in:8050 or hostname of master:8050?




Thanks in Advance
