#19 default access list is too generous in nickserv

[Peter Palfrader]

Hi,

when registering a new nick in nickserv, it also puts
the current host into its access list.

if I come from a host without reverse dns, it appears
to use some class based voodoo.

for instance: it picked "~weasel@62.*" because I come
from some host in 62/8.

Given that classes are dead for years now, and CIDR is
used everywhere, it's probably not a good idea to make
it that generous. Maybe just use the entire ip address?

thats not ideal either. sometimes dynamic hosts have broken
hostnames adn they will end up with too large accesslists.

using /24 doesnt seem ideal either. /16 seem to large.

maybe using /24 for a short time approach seems best, with
another cool fix at the other end. (for example some SQL db
which rips off RIR Data and then comparing the used ip
against allocations or so - the first part shouldnt be the
problem, ive done that with ripe before.).
