Comment 139 for bug 128803

Yes: what normally there was (at least, when /etc/hosts was written by hand):

127.0.0.1 localhost my_fancy_hostname_not_qualified_here

...and if you have a fixed IP:

127.0.0.1 localhost
10.1.2.3 hostname.domain

...and on our Debian server it's still like that. This "127.0.1.1" thing is quite new for me. I do not know why it should make a difference, but still, it's strange. I suppose an interaction with the name service.

In effect (without any change, with the 127.0.1.1 entry in /etc/hosts):

(0)pern:~/www/DEAROOT% host 127.0.0.1
1.0.0.127.in-addr.arpa domain name pointer localhost.
(0)pern:~/www/DEAROOT% host 127.0.1.1
Host 1.1.0.127.in-addr.arpa not found: 3(NXDOMAIN)

So there is a difference. Really puzzled.
