However, today I noticed something strange, which doesn't look entirely normal to be, but has also never caused problems - at least not that I know. Here's what I'm talking about: When I was routinely changing the configuration of the Ethernet interface on my ppp-enabled machine, I entered "ifconfig" and saw something like that: root@colt> ifconfig ep0: flags=8843 mtu 1500 inet 192.168.0.1 netmask 0xffffff00 broadcast 192.168.0.255 inet6 fe80::210:5aff:feb3:1695%ep0 prefixlen 64 scopeid 0x1 ether 00:10:5a:b3:16:95 media: Ethernet 10baseT/UTP lo0: flags=8049 mtu 16384 inet6 ::1 prefixlen 128 inet6 fe80::1%lo0 prefixlen 64 scopeid 0x2 inet 127.0.0.1 netmask 0xff000000 ppp0: flags=8010 mtu 1500 faith0: flags=8000 mtu 1500 tun0: flags=8051 mtu 1500 inet6 fe80::210:5aff:feb3:1695%tun0 prefixlen 64 scopeid 0x5 inet 192.168.0.1 --> 10.0.0.2 netmask 0xffffff00 inet 212.68.69.166 --> 255.255.255.255 netmask 0xffffffff inet 212.68.71.5 --> 255.255.255.255 netmask 0xffffffff inet 212.68.69.218 --> 255.255.255.255 netmask 0xffffffff inet 212.68.71.25 --> 255.255.255.255 netmask 0xffffffff inet 212.68.71.9 --> 255.255.255.255 netmask 0xffffffff inet 212.68.69.217 --> 255.255.255.255 netmask 0xffffffff inet 212.68.69.252 --> 255.255.255.255 netmask 0xffffffff inet 212.68.71.58 --> 255.255.255.255 netmask 0xffffffff inet 212.68.71.12 --> 255.255.255.255 netmask 0xffffffff inet 212.68.69.204 --> 255.255.255.255 netmask 0xffffffff inet 212.68.69.219 --> 255.255.255.255 netmask 0xffffffff inet 212.68.71.33 --> 255.255.255.255 netmask 0xffffffff inet 212.68.69.176 --> 255.255.255.255 netmask 0xffffffff inet 212.68.69.235 --> 255.255.255.255 netmask 0xffffffff inet 212.68.69.233 --> 255.255.255.255 netmask 0xffffffff inet 212.68.69.206 --> 255.255.255.255 netmask 0xffffffff inet 212.68.71.31 --> 255.255.255.255 netmask 0xffffffff inet 212.68.69.151 --> 255.255.255.255 netmask 0xffffffff The list goes on for quite a few lines for the tun0 interface, and that makes me wonder what's going on here. Seems like there are many IP addresses connected to tun0. I do get a dynamic IP address on every dial-in and it seems as if the whole list of IP addresses that have ever been asigned to me is being listed by ifconfig for the tun0 device. But why is that so? Shouldn't there only one IP address be listed, i.e. the one I have been assigned for the current ppp connection? And shouldn't that address be deleted again after hanging up the current connection? Any comments are welcome! Probably there's something wrong with my configuration, but I haven't played with it for quite some years, and interestingly, besides what I posted above, there have never been any noticable problems.
