Thanks for your answer!

The status (the NOERROR in this case) actually serves the purpose of saying that the connection to the DNS server is ok. I wanted a way to correctly split this ressource record so i could extract every field if i wanted to.... I could then use this to extract every DNS message NOERROR, NXDOMAIN, SERVFAIL, etc treat them accordingly.

What if i could keep my RS the same BUT use an empty line as a split delimiter?

That way i could have block[1] like this:

Code:

;; ->>HEADER<<- opcode: UPDATE, status: NOERROR, id:      0
;; flags:; ZONE: 0, PREREQ: 0, UPDATE: 0, ADDITIONAL: 0
;; ZONE SECTION:
;exemple.local. IN   SOA

And so on and so on so i would know that if block[4] exist i have a failed update?
