Bell canada CIDR

Hello,

We received a /21 from ARIN a year or so ago which we have been using. At the time I noticed Bell was advertising a longer CIDR which included ours. I contacted Bell, they said it would be corrected, multiple times.

Who I might contact to have this resolved?

Thanks for your time,
greg

shorter cidr.... less specific route. it shouldn't matter, unless
someone filters the more specific...it's not nice of them, for sure.

few bell.ca folks who read nanog...

Contact everyone who peers with them and ask them to filter their
illegal route :slight_smile: Or ask them to ask Bell Canada to fix their
misconfiguration.
