"localhost resolution is handled within DNS." in 'hosts' file (1 reply)

Hello.
I am new here and on my way to install WampServer.

But I stepped upon a problem:
The installation process tells that the 'hosts' file in 'Windows\System32\drivers\etc' must have the following entries:
127.0.0.1 localhost #for IPv4
::1 localhost #for IPv6

However, my 'hosts' file contains this comment instead:
# localhost name resolution is handled within DNS itself.
# 127.0.0.1 localhost
# ::1 localhost

Should it just be uncommented, or are changes to the DNS needed?
