Re: RR distribution by type?
The distribution might vary widely by depth, etc., of the zone. You could probably start a survey by using the publicly available high-up zones (root, arpa, etc.). Not to be facetious, I'd be curious what the distribution is in .com (percentages would be good enough). This would impact a lot of areas - some places are sensitive to how many zones a server serves (ie the ratio of NS to glue A's).
