#NetBlock
I blocked a xx.yy.0.0/16 netblock which was heavily crawling the #PixieReport site and latency immediately improved.

Not sure if I should try re-doing the URL space to discourage endlessly crawling the nearby locations links.

Oh joy... found a new Chinese owned netblock (10.47.47.0/24) out of SG abusing the internet by scraping while pretending to not be a scraper. Bye bye, BytePlus (owned by ByteDance, whose bots were already on everybody's bad bot lists) BytePlus seems to evade Anubis as well @techaro.lol

I tried an AI assistant today. I asked the agent to reformat a list of IPs and to resolve the netblock owner. Everything looked great. Then I double checked the answers. About 20% were delusions

I see you using NordVPN to try to hide your IP address to -try- to attack my client's stuff.

*sends all traffic for the entire netblock to /dev/null/*

Keep it up. It's fun.

The Nepenthes instance that's running test code straight out of SVN has been holding about 140 connections open at any given moment, for days now.

Looked at the logs and noticed a trend.

For science, I added a rule to drop 146.174.176.0/18 at the firewall level. It's a netblock advertised from […]

the ddos spam stuff has gone after datacrystal now, and (since it's a much smaller serveR) it was more or less constantly down.

applied some of the same things as tcrf and it is back to normal.

love it when most of the abuse is coming from Microsoft's netblock :')

But since I'd rather code than complain, I updated graymilter to handle netblocks - sort of. It already had a way to specify a list of addresses and netblocks to always allow. I changed that to handle multiple lists, and used it to deal with the netblock […]

...nothing like throwing a few /12 netblock IP bans in your web server config because some asshole on alibaba's network is scraping your git server at a rate that's running it into the ground. fuck these (probably) GenAI-feeding shitheads…

But hey, "Tier-1" *and* I did get my new netblock, even if the Tech Support guy was a bit confused on some of the finer points of networking. 🧐

(iii) anything regarding CIDR notation 😱 (when I was reading the new netblock back to him, I read off the starting IP address, and put a "/28" on the end of it -- and he had to correct me by saying that "there is no '28' on the end" 🙄)

(i) what a "netblock" is 🤔 (okay, I'm a dinosaur, and that's probably an outdated term; these days, all the kids are calling it "your range of static IP addresses," which is way too many syllables for me)
(ii) what a "routable" IP address is 😳

What's funny is that this was, of course, Tier-1 Tech Support ("Is your router plugged in? Are any of the lights on?"), and this really nice guy, who was supposed to be helping to convey to me what my new netblock is, apparently does not know:

I use exim and likewise have few problems. Occasionally get put on a list somewhere purely on
the basis of my netblock, even though I have reverse DNS set up properly. I've never set up DMARC, but I probably should

Thankfully their DNS records are still in-tact, and that same IP also points to noaa.gov (which at the time of writing is still operational). But it's just a small sliver of hope -- not liking how things are looking :(

@simon because, by convention, the first address in a netblock of any given size is assigned to the default gateway/router, and the last is the broadcast address?
January 30, 2025 at 8:23 PM
Here's a networking problem that I came across today. An ISP has a /19 netblock. Is there any technical reason why they shouldn't give out the last address in that block (xxx.xxx.255.255) as a customer address? #networking #ipv4 #cidr

I am dying to find out if they planned to keep Lemon8 operating (otherwise why spend so much effort getting influencers to push tiktok users to it) but it had a dependency on some database inside tiktok and Oracle et al just yanked BGP for the whole netblock.
