hosts file not being taking into consideration

[Frederic Muller]

Hi!

Using F25 and as the title mention when I add an "IP  domain" into my
hosts file it doesn't seem to work anymore. It has worked consistently
even under F25 until recently. Ping however works fine (in the sense it
is replying with the IP set up in the hosts file.

I did some googling but all the solutions I found didn't seem to work
neither (and not Fedora specific). Any idea what could be the problem?

Thank you.

Fred
