script to undo CNAME mapping. if line maches CNAME www.libreoffice.org, then print A, AAA, MX and corresponding TXT records and skip to next line , otherwise just print the line as-is.

awk '/CNAME *www.libreoffice.org/{ printf "%-25sIN A       89.238.68.168\n%-25sIN AAAA    2a00:1828:a012:168::1\n%-25sIN MX 10   bilbo2.documentfoundation.org.\n%-25sIN TXT     \"v=spf1 a:bilbo2.documentfoundation.org ?all\"\n", $1, $1, $1, $1; next } {print }' < cname_dnsrecords.lst  > dnsrecords_fixed.lst
