Registries will limit the number of hosts returned from an IP address
query. This limit might be lifted should the registry offer different
classes of service for consumers such as law enforcement agencies etc.
Knowing the limit has been reached would be useful.

One should note that Base Agreement & Specifications (Specification 4) of
the new gTLD Applicant Guidebook
<http://newgtlds.icann.org/en/applicants/agb/base-agreement-specs-11jan12-e
n.pdf> requires Registries to provide name server responses for IP address
input.
