having a consistent Passive DNS output format is that multiple client
implementations can query different servers without having to have a
separate parser for each individual server. [http://code.google.com/

"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in RFC 2119 [RFC2119].
2. Limitation
As a Passive DNS can include protection mechanisms for their
operation, results might be different due to those protection
measures. These mechanisms filter out DNS answers if they fail some
criteria. The bailiwick algorithm (c.f. http://www.isc.org/files/
passive_dns_hardening_handout.pdf) protects the Passive DNS Database
from cache poisoning attacks [ref: Dan Kaminsky]. Another
limitiation that clients querying the database need to be aware of is
criteria. The bailiwick algorithm (c.f.
http://www.isc.org/files/passive_dns_hardening_handout.pdf) protects
the Passive DNS Database from cache poisoning attacks [ref: Dan
Kaminsky]. Another limitiation that clients querying the database
need to be aware of is that each query simply gets an snapshot-answer
of the time of querying. Clients MUST NOT rely on consistent
answers.
