NAME

fpdns - DNS server fingeprinting tool

SYNOPSIS

fpdns [ -d ] [ -f ] [ -F nchild ]
[ -p port ] [ -Q srcaddr ] [ -r retry ]
[ -s ] [ -S separator ] [ -t timeout ] [ -v ] [ server(s) ]

DESCRIPTION

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 .
