Incorrect results for DNS based asn lookups when a local searchdomain is in effect #324
Description
In net.py the cymru domain is set as follows
IPV4_DNS_ZONE = '{0}.origin.asn.cymru.com'
IPV6_DNS_ZONE = '{0}.origin6.asn.cymru.com'
It should be set to this:
IPV4_DNS_ZONE = '{0}.origin.asn.cymru.com.'
IPV6_DNS_ZONE = '{0}.origin6.asn.cymru.com.'
On my system there is a local search domain set which is appended after cymru.net and leads to the following error.

I will make a PR for this change.
