[PLUG] Need to enumerate all the subdomains of a series of IPv4 addresses

[george@georgesbasement.com]

While trying to make an estimate of the number of domains under the 
control
of a specific CIDR range (acually, about twenty of them) I ran afoul of 
the
query limit at Hurricane Electric and find myself shut out for a week.

What caused the over-run was that HE limits the number of domains in a 
listing
to 1,000 and truncates all the rest. I fell back to the practice of 
looking
up one IPv4 address at a time, which quickly exhausted the 288-query 
limit.

Is there an alternative search method ? Googling wasn't very productive.

The CIDR ranges are all under Russian control, by the way, so some of 
the
Google search results I got were all in Russian ...

Here's one result that Hurricane Electric gave me; I'd want to replicate 
that
as a test:
193.124.176.133 PTR: coderlabs.ru 	A: 2daymarket.ru, akexpert.ru, 
antiden.ru, avtodov.ru, avtolombardplus.ru, churchill-rest.ru, 
coder-team.ru, coderlabs.ru, darsad.ru, doorkzn.ru, e-vid.ru, 
elitegrupp.ru, fogprofi.com, greatwallshop.ru, hcvolna.ru, if-sk.ru, 
imageteam.ru, inomarka16.ru, inomarkastore.ru, isitdikov.ru,
