The following resolvers are built into the network manager:
- en_ionet—broadcast requests for
  name resolution on the LAN (similar to
  the TCP/IP ARP protocol). This is the default.
- dns—take the node name, add a dot
  (.) followed by the node domain, and send the 
  result to the TCP/IP
  gethostbyname()
  function.
- file—search for accessible nodes,
  including the relevant network address, in a static file.
