According to my calculations and test with bind9 and nsd it should and
we should be able to add two more before we reach the limit. If I am
miscalculating something lemme know.
I used http://www.rfc1925.org/root.zone as base for my calculations.

* Current state (A.NS - F.NS; E.NS is only IPv4) *
;; MSG SIZE rcvd: 359
* Current state (A.NS - F.NS; full dual stack): *
;; MSG SIZE rcvd: 387
* +1 NS (A.NS - G.NS; dual stack) *
;; MSG SIZE rcvd: 447
* +2 NS (A.NS - H.NS; dual stack) *
;; MSG SIZE rcvd: 507
