Rezopole sets up a publication service of correspondence between IP and AS. A simple DNS request allows to find the AS and the subnet in which the IP is published!

This new public service is an alternative to the American team-cymru and allows to expose BGP routes seen from Europe. Visit www.rezopole.net/mapping-ip-as to enrich your network scripts! These tools (dig and asdig) are reverted to the public domain on our github! An update is coming…

The Rezopole technical team now shares its network tools software developments on a github repository. Two projects are already published: lint_conf and capstat.

"Lint_conf" is a tool aimed at looking for declaration inconsistencies in the switch or router configuration using the "IOS " (Cisco, Brocade, Dell, BDcom) syntax. This tool is particularly advantageous when validating configurations of more than 22000 lines!

"Capstat" is a network traffic statistical tool. Its strength is in being able to aggregate and cross the content of a "libpcap" (tcpdump/wireshark) capture with a full-view from a router and to obtain the traffic matrix per AS (which AS to which AS). It also provides crossings on more immediate criteria: by arbitrary length prefix, by involved MAC addresses, etc....

Each of these projects is already today implemented in the public domain via the GPLv2 license. Any contributions are welcome: functionality suggestions, bugs reports, code additions or corrections. To your keyboards!
