@mary @ExpiredPopsicle okay, so the <zero/> and <one/> part is what it is, but one thing actually got my attention: "if a server supports Binary XMPP it advertises a special DNS SRV record _bxmpp._tcp"

And I got curious: Does XMPP uses DNS for anything real? Yes it does! It totally does :)

@mary @ExpiredPopsicle there is more info here: https://wiki.xmpp.org/web/SRV_Records

but I think the tldr is, that XMPP clients need to query those DNS records in order to figure out how to connect to a domain/XMPP server + specifying backup domains.
