Most of your replies seem not to address the (immediately

Hi All,
I doubt any legal action would have any chance, of cause depending on
the country's law your using. The server is publicly accessible.
It's like prosecuting somebody for knocking on your public front door
to ask the way. (or for that matter salespeople) You only might have a
chance to put

Somebody who has irresponsibly (and apparently wantonly, given his
refusal to fix it) delegated his domain(s) to your DNS server is
essentially causing a (modest bandwidth) distributed denial of service
attack on your server. I don't think that the "responsible" thing to do
is to sit there and

Is it possible to get BIND not to respond at all, thereby causing
a timeout on the query? That would perhaps reduce load more than
NXDOMAIN or deleting the sone(s) would.

What noise?
Your post is to the point and appropriate, lots of members of this list
may be in this situation and ignore it because they have NFI on what to
do, so you've helped them.
Though personally I have done a few times
You could ask the registrar/root domain admins to point those domains
somewhere other than your server; or just delete them from the root
servers at their perogative. You might want to give your ex-customer a
final warning beforehand as to your intent. It might spur them into
actionand maybe

You should just be able to ask the registries to remove the delegations
in a sane world as per RFC 1033.

Unfortunately I don't think that there is, other than the nuclear option of
becoming authoritative and pointing them elsewhere.
That would be a jackass move though.

yes, but it minimizes the use of resources because the only answer is nxdomain.

Hi,
We had a former customer who parked about 300 domains with his
registry on our server but is no longer a customer and hasn't moved
his domains. There aren't any hosts behind the domains.
Is there anything more I can do to block/prevent them from continually
querying my system outside of just
29 matches
