I would say stick to VLSM only, not the non-VLSM CIDR. Not practical.
Les, where are you?

Sorry, been teaching at IBM. Yup, I would think that VLSM can be useful in
the kinds and sizes of networks where Linux admins work. CIDR is much more
pertinent in core routers at *large* ISP's, and while I understand the
theory behind it - which is basically VLSM over the entire Internet - I've
never had to use it in a practical sense.
How about the proxy ARP hack - should a level 2 LPI admin know that? Useful
when you introduce stuff like 802.11a but can't have a separate subnet.

is IPv6 that much in use? Still _very_ experimental from my

practical.

Ditto: my teaching of IPv6 is very much along the lines of an IBM salesman
- tell them how good it's going to be when they eventually get it. I don't
know of any ISP in Australasia offering commercial IPv6 access. In fact, I
only know of one IPv6 backbone site in Australia (Trumpet Software -
remember Trumpet Winsock?). IPv6 barely registers on my radar.
It's not really experimental; it's just that most folks are putting off the
pain through NAT techniques and RFC1918.
Agreed on bandwidth limiting, also traffic shaping etc., especially in an
ISP environment, which is probably the biggest market segment for Linux,
historically.
