I am planning to use the MVPS hostfile (windows vista). In the existing host file entry, there is a following line,

"::1 localhost"

on the other hand, MVPS hostfile does not have such a entry. What is the significance of the above entry? and is it okay not to have it? or should i copy this line to my MVPS host file?

I personally don't use a Hosts File, see this thread for some useful info, post #11 in particular.


Hope this helps :thumbsup:.

It is IPv6 notation. Implies that IPv6 is running on our computer.
http://en.wikipedia.org/wiki/.localhost
So it's normal.
Question is whether the HOSTS file which redirects scumware to localhost IPv4 address, 127.0.0.1, is relevant to IPv6. I don't know the answer.

Edited later:
Here's some data about IPv6
http://msmvps.com/blogs/robwill/archive/20...osts-files.aspx

For the record, the Hosts file can also be used for IPv6 addressing. Vista for example includes the IPV6 localhost entry, by default:

::1 localhost


and finally, the official descriptions

The HOSTS file is a text file that has no extension and can be viewed using notepad. At the top is an explanation of the simple syntax. Each line is an IP address, a domain name, and an optional comment placed after a # sign. A HOSTS file maps an IP address to a name. 127.0.0.1 localhost is the universal IP address of all local computers and is the standard hostname given to the address of the loopback network interface which refers to the local computer only.

The original purpose of hosts files was to map the proper address to a site's name but now its also used for blocking purposes. The loopback address is used to stop web ads from displaying because 127.0.0.1 indicates home (the location of your computer) and whatever is redirected home will not leave the system. Anything that appears in your HOSTS file without an # at the beginning, except from the "127.0.0.1 localhost" line, should be viewed with suspicion. In Windows Vista the IPv6 localhost is ::1 localhost by default. Please read Hosts File FAQS.
