   7 This basic example shows how to create a context and resolve a host address (DNS record of A type).

  12         import unbound
  13
  14         ctx = unbound.ub_ctx()
  15         ctx.resolvconf("/etc/resolv.conf")
  16
  17         status, result = ctx.resolve("www.google.com")
  18         if status == 0 and result.havedata:
  19                 print "Result.data:", result.data.address_list
  20         elif status != 0:
  21                 print "Resolve error:", unbound.ub_strerror(status)

  23 In contrast with C API, the source code is more compact while the performance of C implementation is preserved.
  24 The main advantage is that you need not take care about the deallocation and allocation of context and result structures; pyUnbound module do it automatically for you.

  26 If only domain name is given, the :meth:`unbound.ub_ctx.resolve` looks for A records in IN class.
