On disk, less than 60 kilobytes:

% wget --quiet ftp://rs.internic.net/domain/root.zone.gz
% gunzip root.zone.gz 
% wc root.zone 
 2171  6544 57305 root.zone

Probably a little more in BIND's memory.

You are kidding or you add the data of all DNS servers in the
world. If the DNS is decentralized, it is for a reason.
