fpdns is a program that remotely determines DNS server versions.
|
||
|
|
It does this by sending a series of borderline DNS queries which
|
||
|
|
are compared against a table of responses and server versions.
|
||
|
|
|
||
|
|
False positives or incorrect versions may be reported when trying
|
||
|
|
to identify a set of servers residing behind a load-balancing
|
||
|
|
apparatus where the servers are of different implementations, when
|
||
|
|
a specific implementation behaves like a forwarder, behind a firewall
|
||
|
|
without statefull inspection or without Application Intelligence.
