Whenever something doesn't work, it's generally the DNS. That's why we (re)introduce The Phone Book of The Internet.

News - The Phone Book of the Internet

A handy booklet with the domain names and IP addresses you need, to keep everything working even when the DNS doesn't.

@koenvh It's going to take me a while to get through all that.

@koenvh Good one 

Bound version of Unbound

Yay! I am in the phonebook too!

@koenvh Does it do v6?
@Zugschlus @koenvh I imagine that'd be hard to do if only because the address space is so much larger. You can scan all of IPv4 in like, 20 minutes.

@koenvh @nlnetlabs I am seeing a distinct lack of IPv6 support 🤔
@sindarina @koenvh @nlnetlabs That was my immediate first thought as well, and I'm not sure why I knew off-hand that nlnet.nl had IPv6. 🤔
@koenvh It is legitimately really fun to look through it to find domains you're faimiliar with!
@koenvh can I get a physical copy in a 5,25 floppy disk?
@koenvh honestly i'd buy one if you sold them... just for the gimmick
@kate I'm looking at actually getting it printed, but ~3200 pages is a bit more than most companies are willing to print. If I do find one that will I'll let you know.
@koenvh maybe every 10th page would be enough, just to avoid using so much paper!

@koenvh

Would it be possible to publish it in the form of a text file that's compatible with /etc/hosts ?

@TheLancashireman That would be really quite simple to do, though I fear people would actually start using it (and I like IPv6 too much for that)

@koenvh

My router and provider prefers IPv6 when it's advertised.

An IPv6 version would be great!

@koenvh wait

why is my IP wrong 

@koenvh ah, it’s the old one, should have changed that a few days ago instead of

uh

yesterday

@xerz Don't worry, the TTL is a year (or however long households keep using the old copy), so next year it should be correct! ;-)
@koenvh I love the three consecutive pages of domains all starting with "sex". truly one of the domain prefixes
@koenvh what the fuck I'm not on there why is my name nowhere :(

phone book without me or my friends
@sodiboo @koenvh I'm in there! well... one of my silly old domains is...
@dracoling @koenvh I looked for my domain that's been registered the longest, figuring maybe the dataset is older than sodi.boo, but my other domains also aren't in there :(
@sodiboo @dracoling It uses the top 1,000,000 domains from Cloudflare Radar, so less popular domains are not in there. You can always call our resolver though to get the IP address :-)
@koenvh @dracoling ah, that would explain why I'm not in there. :3
@koenvh @dracoling I just looked again and did actually find this instance domain in there! omg I am in there after all just not my name only the gay sex dot cloud. is this how I will go down in history
@koenvh But the IP address for artemislena.eu keeps changing :/
@koenvh (tbf it's also not in there)

@koenvh the phrase “Think of it as a bound version of Unbound.”

am. dead. :D

@koenvh you should put this on a print-to-order manufacturer like Intel does for the x86 manuals, it'd be really funny
@koenvh so many casino* domains 🤑🤑🤑
@koenvh Re v6, I called. 24 hour service. Am very relieved their telephone hotline sraff can give you the corresponding IPv6 address for any domain you wish to know about. Just call. 10 out of 10 for customer support!
@koenvh ah yes, the "porn1.sex" is the domain that I would definitely had need

@koenvh um, do you happen to know what would result in one getting on the list?

because (un?)surprisingly both this fedi instance and my website are absent from that list lol

@awoo It uses the Cloudflare Radar top 1,000,000 domains, which bases its data on the Cloudflare public resolver. So get 1.1.1.1 to resolve your domain name many times and you should appear in the list.
@koenvh huh! I kind of doubt that many people stumbling across https://wolfyja.de will use Cloudflare's DNS but it's still fun to at least see apicrim.es (no subdomains though) on that list ^^
jade arson.

@awoo @koenvh The footnote says it's pulled from Cloudflare Radar

@koenvh legend has it that in The Olden Days (before DNS) our director of computing would have his secretary print out the hosts* file once a month. He kept it on his desk for reference.

(This was the hosts file for the whole internet)

This is a list of substantial, commercial-or-social-good mainstream websites which provide onion services. - alecmuffett/real-world-onion-sites

@koenvh I am picturing a version of this where each ip belonging to #cloudflare is highlighted orange,
red for #AWS,
blue for #azure,
green for google cloud.

would really help illustrate how centralized the internet really is.
