I was not precise in speaking of "IP", I meant "ISP".
Here is how I proceeded :
# ppp
User Process PPP. Written by Toshiharu OHNO.
Using interface: tun0
Interactive mode
ppp ON ns> dial simplesite
Dial attempt 1 of 1
Phone: 0836019301
dial OK!
login OK!
ppp ON ns> Packet mode.
ppp ON ns>
PPP ON ns>
# ifconfig -a
tun0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1500
inet 193.252.160.71 --> 195.6.71.4 netmask 0xffffff00
sl0: flags=c010<POINTOPOINT,LINK2,MULTICAST> mtu 552
ppp0: flags=8010<POINTOPOINT,MULTICAST> mtu 1500
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
inet 127.0.0.1 netmask 0xff000000
# netstat -nr

# ping 195.6.71.4

# ping ftp.freebsd.org
ping: cannot resolve ftp.freebsd.org: Host name lookup failure
If a hostname is useless for outgoing connection ( I don't expect any
incoming one ), can I choose any hostname I like ? That'll be great !
