When a block of IP addresses or a collection of domain names becomes associated with bad action -- spamming, jabbering, denial-of-servicing -- various ad-hoc Internet groups will add it to a blacklist of "rogue IPs" or "badware domains" that are blocked at a very low level in the network.
The problem is that there doesn't seem to be any way to readily diffuse an "all clear" signal to everyone who follows along with this block, which means that gradually, the net is acquiring "slums" -- blocks of useful space that can't be occupied by legitimate users because someone bad once lived there and now no one will accept their traffic.
The Washington Post's Security Fix visits this question -- it's a compelling problem when you think of it. Bad actors will continue to move from blocked IPs to fresh ones, and if we never release the blocked sections, eventually we'll have shut down a very large chunk of IP space indeed.
"The problem is once an address block gets so polluted and absorbed into all these blocklists, it's difficult to get off all of them because there is no central blocking authority," said Paul Ferguson, an advanced threat researcher at Trend Micro. "That space won't be toxic for all time to come, but certainly it is going to be tainted for whoever ends up with it..."

"What you'll find is some blacklists out there are derivatives of other lists, and it's hard to get those cleaned up," Bertier said, recalling a case last year in which a customer was given a swath of Internet addresses, only to find it was impossible to send e-mail from that space. "Typically in those cases, we'll work with the customers to get them new space and mark that allocation as something that really shouldn't be used for e-mail."
California assemblyman Jim Cooper (D-9th) has copy-pasted New York assemblyman Matthew Titone’s (D-61st) insane, reality-denying bill that bans companies from selling smartphones with working crypto on them, introducing nearly identical measures in the California legislature.
Trumpscript — a python variant — only allows numbers over 1,000,000; has no import statements (all declarations must be homegrown); only has integers because floating-point numbers are un-American (America never does anything halfway); only allows popular words and the names of politicians as variable names; limits error messages to direct Trump quotes; and requires that […]
“Radical ecology” has come to mean a kind of left-wing back-to-the-landism that throws off consumer culture and mass production for a pastoral low-tech lifestyle. But as the brilliant science journalist and Marxist Leigh Phillips writes in Austerity Ecology & the Collapse-Porn Addicts: A Defence Of Growth, Progress, Industry And Stuff, if the left has a future, it has to reclaim its Promethean commitment to elevating every human being to a condition of luxurious, material abundance and leisure through technological progress.
Plastic is so 2013. You don’t want to buy something only to throw it away or lose it and barely care. You like nice things and want to hang onto them. The Plazmatic lighter here is a high quality, high tech alternative to the typical cheap, plastic lighter you get at the old gas station. […]
Real engineers build things. Super cool engineers build things with their hands and fingers, like our engineering forefathers did. No idea where to even begin to do that? This step by step Arduino course is now 92% off and is going to get you up and running, from zero to hero, in no time. So […]
How do Google and YouTube really work? It turns out, Python kind of runs things around those parts. And with this bootcamp, you’ll get whipped into shape and ready to start programming yourself. Whether you’re a Python pro and just want to sharpen your skills, or a total tech newbie with little or no coding […]
