Problem with old b.root-server and DNS


You notice errors in the DNS accompanied by messages in your logfile like:

checkhints: ( extra record in hints


checkhints: ( missing from hints

and there are requests to an old b.root-server.


Please check if your update is older than 4 years:

grep update /etc/bind/db.root

You might see something like:

last update: February 17, 2016


You can easily fix this bug by doing

wget -O/etc/bind/db.root
