>"Abuse cannot not provide you a list of websites that may be encountering >reduced visibility via Cogent" They could, if they kept a list of forward lookups they had done to get IPs that ended up in their blacklists. But just having the IPs it's impossible to get the whole list of possible hostnames that point at it (reverse records are singular, and often missing). Nonetheless, it'd be nice to know how a single IP got onto the list - and what Cogent's doing about situations where multiple other hostnames map onto the same ip. I have clietns that are Cogent customers, I'd just like to get informed before I bring the hammer down. /kc -- Ken Chase - math () sizone org Guelph/Toronto Canada Heavy Computing - Clued bandwidth, colocation and managed linux VPS @151 Front St. W.
