[dns-operations] Tool to store zone file with TYPExxx records

[Klaus Darilion]

Hi!

When doing an AXFR with dig, it stores all known RRs with their nice
name. Only unknown RRs are stored as TYPExxx.

Does someone know a tool which stores RR as TYPExxx, or convert zone
files to TYPExxx?

Usecase: ie a zone with new fancy records AXFRed with new fancy dig, but
later processed by some old tool which complains about the unknown fancy
new RRs.

Thanks
Klaus
