Both pppd and dhclient can receive information about available DNS
servers, and they will try to make that available to other
applications (by adapting /etc/resolv.conf).
Pppd is even nice enough to revert to the original file after
disconnecting.
Michele> How can I prevent it?
For pppd, the answer has already been mentioned. If you want to
prevent dhclient from changing /etc/resolv.conf, create a file
/etc/dhclient-enter-hooks with the following contents (it should be
executable):
# redefine the function which changes resolv.conf to do nothing
make_resolv_conf() {}
