@miyuru I don't really record that kind of data, bgp.tools actually does not log that much data to mostly steer clear of things like GDPR liabilities.

Exceptions are made for "write" actions to users accounts (basically a audit log) and some page load performance data that is kept a few months so I can see if I am doing a better or worse job over time.

I do want to actually repeat some of these experiments, but I've yet to have the time

While home users can (mostly) change their DNS resolver, the vast majority of them don't.

In a talk last year at nog.fi Alain Durand from ICANN dug down on DNS resolver usage: https://nog.fi/event/1/contributions/6/attachments/2/3/eu-resolvers.pdf

The findings are somewhat interesting, this does mean that "Geo"DNS driven things are still very possible, and actually a reasonably small majority of eyeballs need special casing for public DNS recursors that are more hostile to GeoDNS like Cloudflare's

Obviously the kind of user that changes their DNS to Quad1/Quad8/Quad9 is more likely to also know how to complain if they are being served content from the wrong place, but again it's worth keeping that in mind that most consumer users don't change their DNS.

Biz's however do seem to change their resolver, I assume because they are doing more of the configuration themselves (vs a home user that just has a router with all of the stuff configured out of the box), and are more likely to enter into config DNS recursors that they remember the address of.

@Aissen bgp.tools is basically always doing a /0 ICMP scan for https://map.bgp.tools . I don't think I've observed any serious blocking of that IP address, and anyone who did decide to block based on a single ping every 2 weeks likely does not make a accountable difference to numbers!

In general I believe my network is pretty much as reachable as anyone elses, I do run a commercial service form it and have yet to get complaints about lack of reachability

Out of all IPv4 addresses on the internet (that are BGP routed), Around 9.57% of them respond to ICMP ping!

I think I'm going to call EMF-IX quits for this year.

I'm not really at the point where the cost to hire the marquee (etc) is viable for me, since I don't make the same level of income as I used to. (and I suspect trying to find people to split the costs is enough of a task as running EMF-IX etc)

I really hate this stuff, I know the site does not see the email until I click on it, but it just feels like a timebomb siting at the corner of my screen on every site. Even more so because my email addresses are clearly displayed on the screen, making it a doxxing risk if I am not careful with screenshots

@malwaretech @filippo @dangoodin so I pulled the github keys of 1.4k people who follow me on github, and:

$ cat keys | awk '{print $1}' | sort | uniq -c 
     50 ecdsa-sha2-nistp256
      1 ecdsa-sha2-nistp384
      8 ecdsa-sha2-nistp521
      3 sk-ecdsa-sha2-nistp256@openssh.com
     14 sk-ssh-ed25519@openssh.com
    828 ssh-ed25519
    875 ssh-rsa

P521 is used more than P384, but it's all tiny volumes compared to the actually correct option of ed25519.

I don't think P521 (or, in general ECDSA) keys are that widely used, either that or my followers are smarter or dumber than the average

Being the first user of a syscall (at least as far as github code search can see) in your programming language comes with some nerd cred... and some extremely bizzare bugs that are now entirely my problem to resolve.

Currently dealing with a weird case of hitting a weird getsockopt on a socket, and only websockets breaking down, H2 etc still works, so it's not like I broke bi-directional sockets. Extremely strange.

Maybe I should just stop reading kernel code/man pages and just succumb to learning how eBPF works rather than doing mildly bizzare syscalls/sockopts to get what I want

Of course, inet_aton's other legacy will be all of the "trick shot" XSS / WAF bypasses that it allows, since nearly everything is a valid IP address with that damn function.

During the time where I was the maintainer of a largely deployed WAF product, inet_aton was a constant pain in the ass due to all of the creative ways you could fit IP addresses in places that should not have IP addresses in them.
