According to Cloudflares isbgpsafeyet.com, Cogent has been considered
"safe" and is filtering invalids.
But I have found that to be untrue (mostly). It appears that some days
they filter IPv4, sometimes not, and IPv6 invalids are always coming
through. I know it's Cogent, but curious as to what others are seeing.
