Resolve a name

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

Source code

import unbound

ctx = unbound.ub_ctx()

status, result = ctx.resolve("")
if status == 0 and result.havedata:
    print "",
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 unbound.ub_ctx.resolve() looks for A records in IN class.
