legitimate Russian entities taking over prefixes previously used by poor-reputation hosting providers (and inheriting the reputation baggage that comes with them).

📣 Takeaway: Always check the blocklist status of an IP range before leasing or buying it (use 👉 https://check.spamhaus.org). Be wary of IP brokers with a high amount of live SBL listings.

Thanks to everyone who voted in my "Should I Stop Caring and Let IP Address Reputation Sort Them Out?" https://nxdomain.no/~peter/should_i_stop_caring_and_let_ip_reputation_sort_them_out.html poll.

I have since added the *seriously, folks* note to the exported files and told anybody who wanted out of the big list that I will remove them *on condition that they track down the morons who use that list as anything other than a historical artifact* and *LART* them.

Should I Stop Caring and Let IP Address Reputation Sort Them Out?

? hours left to vote:

I was recently contacted by somebody who claimed to have had their traffic blocked because one or more IP addresses in their range was in the "big list" of #pop3gropers mentioned in https://nxdomain.no/~peter/badness_enumerated_by_robots.html, with the entry dating to before they took over that particular range. That, my friends, is *not* the intended use (that's what the sixweeks list is for).

📱 The IP and Domain Reputation Checker has increased functionality.

Following your requests we have added some further features:

✅ Most recent historical listing information - if your IP address is only listed on the Policy Blocklist, or isn't listed on any dataset, you will now be able to see the latest historical listing relating to it.

✅ Additional information requested - where your IP address has been associated with a proxy, we will be requesting additional information to ensure we can resolve your issue as quickly as possible.

✅ Easy to share results page URL, which will return the latest listing information, even if the results have changed.
