I'm searching for a way for a placeholder in my bind zone files. I found some information on the NULL RR which would be perfect, but wikipedia states it's obsolete by RFC 883. I read through this RFC but could not find any reference for this statement.

Is the NULL RR obsolete or not? Is it acceptable to use it as placeholder?

At the moment I use this:

somename                   IN TXT     "placeholder"
