Every person who has Comcast Business Class as an ISP has a reverse DNS in this range. Apparently, at least 6 of those people are hackers or have set up phishing sites. They should be reported to Comcast, who would almost certainly terminate the accounts and pursue legal action against the offending parties. There's no need to "throw out the baby with the bathwater" and mistrust ALL Comcast ISP customers. That's a bit extreme.
