Show HN: Browse Internet Infrastructure

Nice website, but I feel like calling it "wire wiki" is quite ambitious. Currently, it's a (beautiful) DNS lookup tool, but that's about it. I expected something like RIPE Stat [0], or something like the undersea cable map [1] (based on the "wire" in the name). Also, if you're doing DNS, take a look at resolve.rs [2], they have some nice DNS tools, though not as pretty as yours :)

And since you mentioned scanning the IPv4 address space for DNS servers - I did that as well at a some point for a product I've built (and even have a patent on). The list of servers you're going to get with a naive scanning approach is not what you want. It won't include the servers you probably want (such as the customer-facing DNS servers of ISPs) and will include an insane amount of junk like home routers or weird IoT devices that expose their port 53. Hit me up via the email in my profile if you want to chat.

You're right that it doesn't do the name Wirewiki justice yet. I've got so many things planned to add at some point, much more than just DNS. Check again in 2 years' time ;)

> The list of servers you're going to get with a naive scanning approach is not what you want.

Absolutely right. I'm doing uptime monitoring and a handful of checks (udp/tcp, nxdomain, dnssec, dns filtering) before listing them, but I feel like it could definitely be improved. Would love to talk! I'll send you an email.

Great site. If you don't mind I have feature requests, but feel free to ignore them because OSS is OSS and you shouldn't feel obligated.

1) Include a link to dnsviz.net to check on the DNSSEC status of domains. They've already done all the work and it would be a nice integration.

2) Something that I wish more DNS operators understood is the concept of shared fate between authoritative name servers. Shared fate can come in the form of same AS, same upstream, same parent domain, etc. Operators might think they have redundancy when in fact all their servers are located in the same AS, for example. If there is any way you can highlight this or show this it would be useful.

3) I didn't try looking up a phishing domain, but displaying whether a domain exists on popular block lists would be awesome.

I love your attempt at understanding all the TXT RRs that have spread across the DNS in the last 10 years. What a mess.

You're right in that this is a rabbit hole. You could spend the rest of your life building this and never actually completing it, be careful!

Those are really useful suggestions, thanks!

> 1) Include a link to dnsviz.net to check on the DNSSEC status of domains.

I use DNSViz all the time. They've done a great job of displaying the entire trail and helping debug DNSSEC issues. But it's a bit too detailed for my liking. I'm thinking about how I would add this to Wirewiki. What to show and hide by default, how to format it, etc. Adding something similar is pretty high on my list for Wirewiki.

> 2) Shared fate [...]

I do already show ASNs for A/AAAA records, but adding those to NS and MX addresses as well would be useful. I'm a bit hesitant to add more data to the overview, but a separate page that shows an analysis of shared name server resources could be useful indeed. I've added it to the list.

> 3) displaying whether a domain exists on popular block lists would be awesome.

Absolutely. Already on the list :)

Haha, I've already spent 5 years, and I don't mind to keep going as long as it's interesting and sustainable!

Nicely done. I poke at DNS a bit over at StackFox (https://stackfox.co/site/wirewiki.com), and anyone who’s spent time looking at DNS knows how much work goes into this.

A couple thoughts:

1) Nameserver “redundancy” that isn’t. All the ns1/ns2 setups that collapse onto the same provider or ASN once you follow the trail.

2) Authoritative drift. One server quietly serving an older serial or odd TTL for a while — invisible until something breaks. With global data, quirks like that become obvious.

Anyway, inspiring job. Wirewiki already feels like something that should have existed but somehow didn’t.

You're the second person in these comments who points out faux name server redundancy. Interesting. I hadn't considered it as a major theme, but I'll move it up the list a little.

> Authoritative drift.

This is why I query all authoritative name servers (as well as delegating name servers when querying NS records) in the DNS propagation tool. I haven't seen any other site do this. This feels like such an obvious thing to me, but somehow I'm the only one.

Also: ask me anything.

i remember watching your DNS course, it was very good! Do you have any other resources that you like? where i can learn internet infra, dns or anything. Thanks!!

Oh thanks!

Depends on how you prefer to learn, but here are a few suggestions.

I've heard good things about the Computer Networks book by Tanenbaum and Wetherall, but I haven't read it myself. Very broad and comprehensive. The most hardcore way would be to make reading RFCs your hobby. It can be tough to get through, but if you regularly take half an hour to do it, you'll learn so much. I've recently started a course at https://classes.pracnet.net/, which is good too.

Not they guy you asked but here's a free book https://book.systemsapproach.org (they have more free books on other topics like SDN)

HPBN -- High-Performance Browser Networking -- is an excellent (canonical?) resource: https://hpbn.co

How do you see this positioned against something like MXToolbox? There seems to be a lot of overlap in features as it is today so I'm interested in your longer-term vision for wirewiki.

There are a ton of online DNS tool sites, MxToolbox being one of the largest.

I like the idea of evolution (diversity + selection) applied here. Many people building it differently and letting the market decide what's most useful.

My take on this space is making it a browsable graph instead of 'just' a collection of lookup tools. The internet _is_ a graph, and it often makes sense to inspect linked resources (Domain name -> name server -> IP address, for example).

As for the longer-term vision, I'd like to make this graph as complete as possible. It now only has DNS-related tools, but adding ASNs, BGP data, hosting providers, etc. would make the existing tools more useful with every addition.

Have you considered that this tool is also useful to attackers?

Yes. Ultimately nearly any tool can be used for good can also be used nefariously.

Internet infrastructure data is inherently open. I'm just presenting it in a more useful way. So any motivated actor can access it regradless.

In any case, exposing your IP during these lookups is bad operational security for them. So I would assume they'd prefer not to use Wirewiki.

All that to say: I don't feel conflicted about making these tools.

Would you consider serving this as a CLI tool as well?

I don't think I'll make a CLI for this any time soon.

The main thing I bring to the table with Wirewiki is UX, and I don't feel like I could do that well in a CLI.

Why're "wiki"? Where wiki?

It’s a wiki (loosely defined as an authoritative browsable graph / index) of everything that goes over the wire.

"Wiki" normally refers to user-editable sites, while the graph part is normally implied from being a website. Perhaps Wiregraph would be more accurate? Maybe Wireview? These kinds of networking sites are often called looking glasses, so Wireglass might also work, besides the confusion with the material.

That's not even close to what "wiki" means. Couldn't you have spent two seconds looking up the term that you're using (a community-owned content/knowledge graph that's "collaboratively edited and managed by its audience directly through a web browser") before debasing it?

You've confused "wiki" and "encyclopedia"—getting them exactly backwards. Wikipedia is an online encyclopedia that's a wiki.

You're creating (or, at least, aiming to create) an online encyclopedia. But it's not a wiki.
