"That's very nice but can you email me a copy in Microsoft Word DOCX format please?"
I’m just about to live this hell. On advice from a friend, my response will be a simple one: no, because it doesn’t exist. It was written in Markdown [0]. Here’s a PDF. I’m expecting the usual pushback, and will reciprocate. I’ll let you know how it goes. [0]: https://github.com/johnnydecimal/resume/blob/main/resume.md (Yeah I shamelessly inserted my own résumé.)
Pandoc does a good job of generating docx files from markdown
> Cloudflare.NetworkEngineer Ah, that explains a lot. Not that anyone else couldn't do such a thing, but I feel like even amongst more "hacker" types it takes a relatively specialized background to pull a trick like this (at least statistically; I'm sure there are outliers).
It’s because practical experience with technologies like BGP is difficult to acquire without sufficient capital to run a network. You can of course purchase a /24 and dabble (search HN for blog posts describing exactly that). And you can experiment with large deployments in simulators. But network optimization is inherently more of a practical pursuit than a theoretical one, so most broad and consistent learning oppo…
Fun Fact ; I'm not sure if it was RIP or BGP, but a certain Cisco Founder stated that they wouldnt have come up with the routing protocol if it weren't for Hoffman and LSD.
I think it's reasonable to assume that this whole thing has been a marketing campaign to get people to finally have a reason to switch to IPv6. All kidding aside, IPv6 isn't even required for their website or this traceroute trick. He just set up an in-addr.arpa reverse DNS zone to reverse resolve particular IP addresses to specific values. If you had a block of 20 IPv4 addresses, I don't see anything stopping you fr…
>If you had a block of 20 IPv4 addresses, I don't see anything stopping you from doing the exact same thing. A block isn't necessary at all, even on IPv4. Traceroute can easily show internal address or just be lied to. Just recently we've seen a different example of this on HN: https://news.ycombinator.com/item?id=32566730
IP addresses can be lied about, but reverse DNS still needs your ownership of those IP addresses if I understand it correctly. One would need the provider of those IP addresses to setup PTR records for them.

You're right. I didn't consider we don't control the other side's DNS server.
How would you spoof arbitrary IPs? IIUC it's poked at as the next hop...? (Mhm, embarrassingly out of the loop)
I _think_ that if you know the real source and real destination of an ICMP message, you can just forge back a message with an arbitrary TTL exceeded message, from any "I'm IP address xxx" address. Those can come from a lot of rando IPs because the intent of them is just "at this hop, the TTL ran out", and the hops the original sender wouldn't know anyway. A lot of fake hops would be essentially impossible if you exam…
If you return fake IPs in a traceroute you won't be able to control the reverse DNS which is the point of this exercise.

I think consolidation has also lead to this knowledge/experience, at least among younger engineers, being siloed in larger companies rather than spread out among many smaller companies. I started in the industry when the Internet was still relatively new, and at that time most companies I worked with had their own ASN & address space and were running BGP, whereas nowadays most companies just use the cloud.

You can contribute to the Solana core tech team, with the incentive alignment of underlying token value as a partial backer! I think they're doing some really cool stuff on the network optimization level. As an example, Solana recently implemented QUIC in its latest release: https://github.com/solana-labs/solana/projects/74
Are they still using that hand-wavy "cryptographic proof that a duration of time has passed"?
Here's what it looks like: $ traceroute cv6.poinsignon.org traceroute to cv6.poinsignon.org (2001:bc8:3eff:c0::ff), 30 hops max, 80 byte packets 1 gateway 0.795 ms 0.789 ms [...] 8 hello (2001:bc8:3eff:c0::1) 1.431 ms 1.202 ms 9 My.name.is.Louis.Poinsignon (2001:bc8:3eff:c0::2) 1.649 ms 1.274 ms 10 I.am.a.network.and.systems.Engineer (2001:bc8:3eff:c0::3) 1.695 ms 2.090 ms 11 This.is.my.resume.over.traceroute (2001:b…
Remember when they said we'd never run out of IPV6 addresses? Good times.
they never anticipated the internet of internet of things. What a shame.
