We've been using the older version (pre 9.3) and the underscore in the hostname in A recored like this_machine IN A 123.2.234.4
is okay. We have to upgrade the bind to 9.5 The new version does not like underscore in the hostname Is there any way to workaround ? (otherwise we have to re-publish the web site URL with a new one as the user has used the underscore in its web site for quite some time)
