"TL;DR" is Internet slang for 'Too Long; Didn't Read'. As it's used now, it's a way for someone who has written a long post to provide a very brief summary of what they said (usually no more than a single line) for the benefit of anyone skim-reading the post. Sometimes the summary may be a humorous simplification of whatever was said. > ... How are you "null-routing" all those IPs? With spamdyke somehow? I'm not actually null-routing HostNoc IPs (but believe me, I've been tempted). You could probably use spamdyke to block mail coming from HostNoc customers, because spamdyke's ip blacklisting allows you to blacklist entire address ranges as well as individual addresses. However, when people talk of 'null-routing' an address, it means configuring your firewall (such as an iptables firewall) to simply drop any incoming packets from that source. It's the most absolute form of rejection possible. The other host literally cannot connect to your system in any way, because you've told the firewall "Ignore everything coming from here". Basically, my "TL;DR" was saying "If you refuse to accept any communication whatsoever from this entire chunk of the Internet, it wouldn't be a bad thing". And I was partly joking ... but only partly.
