Why do I see an originating ASN and route announcement when I query for a bogon address?
Some of the routes we learn from partners may contain “leaked” or otherwise bogon routes. The originating network is likely using those routes internally, and they are not meant to be publicly accessible. All routes we publish through our mapping service are presented unfiltered. Note, these routes may be filtered out by other networks so they may not show up in traceroutes, other route monitoring collectors or other online tools.
