Hello Kartik, Well to put that straight I am not much acquainted with drupal except that it is an open source web management system.Checking its installation from http://www.slideshare.net/a_rupeshkumar/drupal-xampp-xp-2-presentation the database port is mostly set to default.In case of drupal this port is 3306 [voila :) ] and also the site name is set to localhost. Now as per wiki * "For IPv4 communications, the virtual loopback interface of a computer system is normally assigned the address 127.0.0.1 with subnet mask<http://en.wikipedia.org/wiki/Subnet_mask> 255.0.0.0. Depending on the specific operating system in use (notably in Linux <http://en.wikipedia.org/wiki/Linux>) and the routing mechanisms installed, this populates the routing table<http://en.wikipedia.org/wiki/Routing_table>of the local system with an entry so that packets destined to any address from the 127.0.0.0/8 block would be routed internally to the network loopback device."
*So this essentially means you can choose any address amongst the 127.0.0.0/8 and run drupal without any problem*. *Now as far as other definitions in hosts file are concerned they deal with configurations related to ipv6 address.For further details you can google it. Cheers , Varun :) * * [Non-text portions of this message have been removed]
