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).
