Editing BIND files with emacs: which mode?

[Stephane Bortzmeyer]

It seems ("bind emacs" is not a good search string in a search engine
:-) that there is no Emacs mode for either BIND configuration files or
for zone files.

For configuration files, the generic "conf-*" modes are OK, for
instance conf-javaprop-mode is quite reasonable.

But for zone files?
