We find out that LLC AB-Telecom´s AS203496 started announcing in november 4th of 2016 the IPv4 block <a href="http://168.197.120.0/23" target="_blank">168.197.120.0/23</a> which belongs to an ISP located in our region -LACNIC, the Latin American and Caribbean Internet Addresses Registry-. <a href="https://stat.ripe.net/168.197.120.0%2F23#tabId=at-a-glance" target="_blank">https://stat.ripe.net/168.197.120.0%2F23#tabId=at-a-glance</a> The IPv4 block <a href="http://168.197.120.0/23" target="_blank">168.197.120.0/23</a> belongs to Operbes, S.A. de C.V.

I had reported to their abuse info but haven´t had any response. Im wondering if someone in this forum can put me in contact with their tech-staff. Thanks in advance for your help, And I apologize if it’s the wrong forum to post.
