1.. _example_resolve_name: 2 3============================== 4Resolve a name 5============================== 6 7This basic example shows how to create a context and resolve a host address (DNS record of A type). 8 9:: 10 11 #!/usr/bin/python 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) 22 23In contrast with C API, the source code is more compact while the performance of C implementation is preserved. 24The 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. 25 26If only domain name is given, the :meth:`unbound.ub_ctx.resolve` looks for A records in IN class. 27
