which provides resolution for localhost as well as your hostname on loopback. I have run across several web apps that want to be able to resolve the loopback address with the hostname. The 127.0.0.2 SuSE has used is a hack and there is talk about doing away with it completely.
The 127.0.0.2 is not just specific to opensuse, its been in use since the Pleistocene in several distros. I suspect it might have been necessary at one time or another in the early days.
I have not seen any talk about doing away with it, but the shortage of IP space would certainly apply pressure in that direction (reducing localhost to a /24 instead of a /8).
Any links to such a discussion?

Ah, well the first is simply a local suse issue and the second is actually a valid use of 127/8 for the specific purpose it was intended for, resolving all sorts of things right back to the local machine. There is no inherent reason that njabl would need many such entries, one would do just the same, and they could have used 127.0.0.1 for all of them. Its simply a book keeping feature, but they all resolve to local host. So the second is actually an argument multiple uses of 127.0.0.x, but nothing they do requires an entry in hosts file, because they rely on the fact that the entire 128/8 block always points to localhost. -- _____________________________________ ---This space for rent--- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
