Well, I am used to install and configure DHCPD in medium networks for easy
configuration of all the clients, so I know what you are talking about, but
I never configured it in order to send unexisting DNS informations.
The IP I think is wrong does not even exist (no ping, no 'dig -x')! It seems
not to be in any way related to my ISP.
I tryed also Windows with this connection and this modem. Well, it's not
surprising that I receive the correct couple of DNS IPs (the two I knew were
the right ones) and I don't get in any way other DNS IPs, nothing in some
way similar to 195.31.88.203 .
In the first post I didn't wrote the real Secondary DNS IP, but be shure,
the right DNS are in a totally different network!
I repeated the test several times (both with Linux and Windows). I always
get one wrong DNS with Linux and two correct (always the same) DNS with
Windows.
Then the question remains open. Is it my pppd working bad or is my provider
sending wrong informations with dhcp? Or is it not even related to pppd and
dhcp (but it seems clear that it has to be)?
If it's my provider fault, how is it possible that I always get a wrong DNS
if I connect with Linux only and get always right ones with Windows?
My provider does not support Linux (as any other here in Italy) in any way,
do I have to think that they send wrong informations to the clients
connecting with Linux only (am I getting paranoid? :-) ?
