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 ...
