Hi!
I use /usr/sbin/ppp to connect my FreeBSD-4.10 box to my ADSL provider.
Each time I connect I am assigned a new dynamic IP address. Sometimes I
notice that an old address lingers on for days (through several
reconnects) like this:
satbsd# ifconfig
<...>
tun0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1480
inet 83.237.41.95 --> 83.237.41.1 netmask 0xffffffff
inet 83.237.23.176 --> 83.237.23.1 netmask 0xffffffff
Opened by PID 32932
<...>
This address - 83.237.41.95 - has been assigned to me four days ago!
83.237.23.176 this is my current address, and I've had a few addresses
in between.
Here is the reconnect log when the old address remained:

This log is perfectly similar to other reconnects, when the address was
changed successfully and the old address didn't linger. Please suggest a
solution to this problem, as some dynamic-ip services refuse to work
because of it.
Thanks,
