Resolve a name

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

#!/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 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 do it automatically for you.

If only domain name is given, the unbound.ub_ctx.resolve() looks for A records in IN class.
