Tool 102: Query a DNS server
Description:
This tool queries a DNS server. For example, it can retrieve IP
address associated to a hostname.
Parameter --dst-ip defines the DNS server address. This server has to
be authoritative for the query requested (or allow recursion, if
--recurdesired is set).
Parameter --name contains the name to query.
Parameter --type indicates the requested information type.
Example: 'netwox 102 server --name www.example.com --type a'
Example: 'netwox 102 server --name 1.2.3.4 --type ptr'
Example: 'netwox 102 server --name example.com --type mx'
Parameter --tcp uses TCP instead of UDP. This is generally not
allowed.
Parameter --dst-ip is the address of remote host/server.
Parameter --dst-port is the port number where to connect.
Optional parameter --src-ip defines the local IP address to use.
Optional parameter --src-port defines the local port number to use.
Optional parameter --ip4opts permits to add IP4 options encoded as
mixed.
Optional parameter --ip6exts permits to add IP6 options encoded as
mixed (first byte is the next header number).
Optional parameters --device, --src-eth and --dst-eth permits to
create a virtual client using fake addresses (in this case, tool have
to be run with admin privilege in order to sniff and spoof at
Ethernet level).
Synonyms:
dig, nslookup
Usage:
netwox 102 -i ip -n hostname -y data [-d device] [-E eth] [-e eth] [-I ip] [-P port] [-p port] [-o ip4opts] [-O ip6exts] [-c data] [-u|+u] [-C|+C] [-T uint32]
