The above is horrible. What that means in practice, is that if you don't
understand what that "funny" slash-number does, you will never be able
to subnet (your or anybody's) networks, you'll get all your reverse
lookups doing strange things and people who see your network setups will
never take you seriously for anything. Supposing an ISP gives you a
block of 4, 8, 16 or whatever IP numbers on a public network and you
went about subnetting the block as above, you'd cause havoc.

Quite another thin is, that learning about it and making it work is
*fun* :)

Best,

Tony
