Since the change in the root has been done, resolvers are starting to
get the new IP address.

If I query RIPE Atlas probes, I see many of them still use the old address 128.63.2.53 :

% python resolve-name.py -r 500  h.root-servers.net
Measurement #3050786 for h.root-servers.net/A uses 500 probes
[198.97.190.53] : 308 occurrences
[128.63.2.53] : 181 occurrences

% python resolve-name.py -r 500 -t AAAA h.root-servers.net
