It's always #DNS, and if it's not DNS, it's the #certificates, isn't it?

Anybody knows where to get good Internet traffic statistics these days? I'm interested in the protocol mix seen in the backbone, not absolute numbers.
What percentage of the traffi is #HTTP, #HTTPS, #DNS

#FRage Vor paar Monaten hatte ich mal das Problem, das ich DNS Einstellungen bei INWX einstellen wollte. Da hat mir jemand einen Tip gegeben, den ich leider nicht notiert hab.
Es geht konkrekt um das einstellen von der IP6 Adresse, ich hab da ne Domain auf ne IP6 weitergeleitet, aber ich kriege kein ping wenn ich diesen auf die IP6 mache.

If anyone from #Kroger happens to see this, your iPhone app has some #DNS borkage. When the app is launched, it queries an A record for "https://​app-measurement[​.]com/sdk-exp" (munged to prevent autolinking here). It's trying to resolve a URI instead of a hostname label.

How does someone trying to find an IP address present a warrant to the dns resolver? Is this a dnssec extension? An AXFR with TSIG/SIG(0)? Or are the warrant & query (and responsive records) transmitted over some other protocol (eg eg dns over postal mail)?

Interesting #DNS issue. I had a domain name with #AWS/Route53 that I registered in 2019 and used until 2021. I shut down the service behind it but kept the DNS configuration intact.
I tried using it again end of 2023, and no matter what I did, DNS resolution was failing.
Now what? I wasn't going t…

(I am not sure if they should be pinned to NS after the first friend resolution, or always authoritatively resolved via petname, or if one should be the failover of the other, or if they should HAVE to agree like DNSSEC)

what does it take to make a special use domain name?
like if .petname became reserved for petname systems?
{friend}.{friend}.{friend}.{protocol}.petname
where {protocol} is picked up by a daemon registered to open that kind of URI, and handles resolving (so it's not just my implementation of petnames)
for example:
alice.peter.david.coolprotocol.petname
david is in my contact as "david: 1.1.1.1"
peter is in david's contacts as "1.2.3.4" (even though I call peter's record "phil")
alice is in peter's record as "8.8.8.8" (even though me and david have alice's that are "2.2.2.2")

This was a fun article to produce. Uncovering Internet activity most overlook, explaining the process, and maybe provoking research ideas. We could do this 24x7.

I've rambled about this before, but services like ClouDNS are the only ways to go for #DNS with high-volume, non-corporate use cases. Running wtfismyip.com/ using

Hmm. Has polyfill.io always CNAME'd to a Chinese domain (presently u855.v.bsclink.cn on BaishanCloud) or is something hinky going on?
