.. _example_resolve_name:
Resolve a name
==============
This basic example shows how to create a context and resolve a host address
(DNS record of A type).
Source code
-----------
::
#!/usr/bin/python
import unbound
ctx = unbound.ub_ctx()
ctx.resolvconf("/etc/resolv.conf")
status, result = ctx.resolve("www.google.com")
if status == 0 and result.havedata:
print "Result.data:", result.data.address_list
elif status != 0:
print "Resolve error:", unbound.ub_strerror(status)
In contrast with the C API, the source code is more compact while the
performance of C implementation is preserved.
The main advantage is that you need not take care about the deallocation and
allocation of context and result structures; pyUnbound module does it
automatically for you.
If only domain name is given, the :meth:`unbound.ub_ctx.resolve` looks for
A records in IN class.
