What is IPWORLDNET and why is it spamming from Canada?

In the October SpamRankings.net for Canada (from CBL data), IPWORLDNET is that big blue molar tooth in the graph on the right. In the interactive chart you can see IPWORLDNET’s Autonomous System (AS) 19875 winning the month with two bursts of spam, and then dropping almost to zero.

That’s not the only spamming churn activity in Canada for October. The log chart shows MetroBridge Networks Corporation AS 25976 METROBRIDGE-NET jumping up from zero to take ninth place. It looks like one organization may have cleaned up its act while another got infested.

Interestingly, longterm winner Bell Canada’s AS 577 BACOM only came in fourth. This is unusual for a national telco. Maybe they’re watching the rankings?
