Are your nameservers in the first class C of your CIDR block by any
chance??? They have been taking CIDR blocks and squirting out
Class C equivilents.Sadly, many poeple (including me) think, oooh, nice big CDIR block lets
put all my important boxes in it's first Class C... Seems to be a
very bad descision ;-(
And, because of the way you get CIDR allocations in Europe (and probably
everywhere else now)
Join RIPE
Apply for space for your own network
This gets allocated from the beginning of a new /19 CIDR block
Build NOC and 1st POP
Then start applying-for/allocating customer address space
I would imagine a very large proportion of "newer" ISPs have critical stuff
in the 1st /24 of their 1st allocation ...
