For starters, rfc5735 [1] tells us that the whole subnet 127.0.0.0/8 is available for loopback purposes (I've used it to test web servers locally, picking one address and giving them a suitable name in /etc/hosts) The 127.0.1.1 seems to be a Debianism explained here [2]. It seems that some (ahem) software (Typical GNOME) wants to know "no, what's my "real" IP address) and fails if there ain't one, so this seems to have been done to pacify those. Bad software, bad. And now go fire your search engine ;-) Cheers [1] https://datatracker.ietf.org/doc/html/rfc5735#section-4 [2] https://www.debian.org/doc/manuals/debian-reference/ch05.en.html#_the_hostname_resolution -- t
