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 :meth:`unbound.ub_ctx.resolve` looks for A records in IN class.
