I guess when I originally sketched a qname minimization algorithm https://mailarchive.ietf.org/arch/msg/dns-privacy/gAgGx9Zz6W0OfyRdJ0Rx7xxmHDg/ I intended that it would slot into the RFC 1034 resolver algorithm https://tools.ietf.org/html/rfc1034#section-4.3.2 which treats QNAME as a variable name rather than a protocol field, so the QNAME changes when the resolver chases a CNAME. That was probably a bad idea: on balance I think it's better to make a clear distinction between protocol fields and variables in algorithms. Elsewhere RFC 1034 uses SNAME for the variable containing the name we are searching for https://tools.ietf.org/html/rfc1034#section-5.3.3 which would be better if it hadn't used QNAME for the same thing elsewhere :-) Tony. -- f.anthony.n.finch <d...@dotat.at> http://dotat.at/ Fitzroy: Easterly 6 to gale 8, becoming cyclonic 5 to 7.
