#svcb — Public Fediverse posts

Missing from @drscriptt 's list are AAAA, HTTPS, and SVCB records.

AAAA has plenty of obvious choices.

You'll know the . convention for SRV, SVCB, and MX resource record sets, of course.

I shall just drop in my personal experience from earlier this year that an accidentally supplied HTTPS resource record can *definitely* break WWW traffic; because browsers in practice do not obey RFC9460 §2.4.2.

There are a much smaller number of people doing SVCB lookups, too. But, interestingly, they are doing them wrongly.

And with a direct correlation to some other abuses.

Which does make me think that, in an ironic twist, it is the bad actors running robot vulnerability probes and scrapers that are the early adopters of SVCB, here.

We now publish DNS HTTPS IP hint records for all #OpenStreetMap web services per #RFC9460 Why? Small incremental improvement to performance and privacy. Our DNS handles over 2,000 requests per second. DNS HTTPS query is our 2nd most common query. #DNScontrol #SVCB 🚀 🤓
