Lots of error messages showing up recently looking like:Jun 27 12:02:23 greenblatt named: checkhints: d.root-servers.net/A (188.8.131.52) missing from hints Jun 27 12:02:23 greenblatt named: checkhints: d.root-servers.net/A (184.108.40.206) extra record in hintsThe hints come from the root-hints file which the resolver software (bind9) uses to know where to start resolving. I checked my db.root, which said:; last update: Jun 17, 2010 ; related version of root zone: 2010061700But it is from the ubuntu 12.04 bind9 package:# dpkg -S /etc/bind/db.root bind9: /etc/bind/db.rootSolution with help from How Do I Update The Root Hints Data File for BIND Named Server? - UNIX fu was getting the latest from ftp.rs.internic.net which now says; last update: March 23, 2016 ; related version of root zone: 2016032301and I should get less warnings now. Comparing the two files shows changed IPv4 addresses for d.root-servers and h.root-servers, changed IPv6 addresses for a.root-servers and h.root-servers and added(!) IPv6 addresses for c.root-servers, d.root-servers, i.root-servers and j.root-servers.
