#dns question about multi-string TXT records: #rfc7208 section 3.3 says they shall be concatenated w/o space.
Is this applicable only to #spf records?
Looking at #rfc9432 (catalog zones) section 4.3.2.1 the group example "operator-y" "bar" seem to suggest this shall be interpreted as some sort of key/value (e.g. “operator-y=bar” or “operator-y bar”) where “operator-ybar” would not make any sense.
Neither #rcf1035 nor #rfc1464 mention multi-string TXT records.

Do yourself a favor and learn the #DNS protocol. I don't mean use a tool. Learn the RFC that make it. 📖 Like #RFC1464.

Sure DNS has limitations. Nevertheless, the amount you can do with one of the earliest backbones of the internet is immense. 🌌 Especially if you understand how the implementation of it works. 😉
