Are you suggesting it's best of the OP creates "l2.example.com" as a sub-zone?

Why it this necessary / safer?
I know of at least 2 commerically-available DNS maintenance systems that, by default, do not allow what they call "dotted hostnames", by which they mean a name which is at least 2 labels below a zone cut, e.g. "foo.bar" in the "example.com" zone. Their underlying assumption seems to be that *every* level of the hierarchy will, in the usual/typical/default case, be delegated.

I don't agree with this assumption in the slightest, but some people are afraid of changing default behaviors...
