oh my great goodness. in RFC 7208 we have this:
3.3. Multiple Strings in a Single DNS Record
As defined in [RFC1035], Sections 3.3 and 3.3.14, a single text DNS
record can be composed of more than one string. If a published
record contains multiple character-strings, then the record MUST be
treated as if those strings are concatenated together without adding
spaces. For example:
IN TXT "v=spf1 .... first" "second string..."
is equivalent to:
IN TXT "v=spf1 .... firstsecond string..."
TXT records containing multiple strings are useful in constructing
records that would exceed the 255-octet maximum length of a
character-string within a single TXT record.
note the lack of a space between the word "first" and the word
"second". this means:
That matches https://kb.isc.org/docs/aa-00356 The RFC referenced in
that article is RFC 4408 instead of RFC 7208.
