domainmonger.com with wildcard NS?

Tue Oct 14 18:07:02 UTC 2003

This is for domain parking. Users can configure their domains (or use a
default I assume) to use these name servers, which in turn point everything
to a parking page. My guess is the parking page is a) down b) fat fingered
IP c) intentionally left blank.

I have seen hosting companies do this to automatically point all domains to
their hosting machines without the need for zone maintenance.

Subject: domainmonger.com with wildcard NS?

This was brought to my attention by a friend.  It looks like
ns1.domainmonger.com and ns2.domainmonger.com are doing wildcard A records
for
all zones, including those that already exist.

If you go to their site and try to register a domain, it properly shows if
the
domain exists or not.

I'm trying to figure out what the reasoning is behind this.

My friend alo pointed out this CERT alert, but I'm not sure how it relates:
