### 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]
