Hi,
Unbound not resolving some domain, but it's works on bind. I have update the root.hint with this wget ftp://FTP.INTERNIC.NET/domain/named.cache -O /var/unbound/etc/root.hints Here is the example : *UNBOUND SERVER :* [root@ns1smg ~]# dig @localhost +trace polri.go.id ; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.47.rc1.el6_8.4 <<>> @localhost +trace polri.go.id ; (2 servers found) ;; global options: +cmd ;; Received 12 bytes from ::1#53(::1) in 1 ms *BIND SERVER :* [root@ns2smg ~]# dig @localhost +trace polri.go.id ; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.47.rc1.el6_8.4 <<>> @localhost +trace polri.go.id ; (2 servers found) ;; global options: +cmd . 501653 IN NS e.root-servers.net. . 501653 IN NS a.root-servers.net. . 501653 IN NS l.root-servers.net. . 501653 IN NS b.root-servers.net. . 501653 IN NS i.root-servers.net. . 501653 IN NS c.root-servers.net. . 501653 IN NS d.root-servers.net. . 501653 IN NS f.root-servers.net. . 501653 IN NS h.root-servers.net. . 501653 IN NS m.root-servers.net. . 501653 IN NS k.root-servers.net. . 501653 IN NS j.root-servers.net. . 501653 IN NS g.root-servers.net. ;; Received 508 bytes from ::1#53(::1) in 10 ms id. 172800 IN NS a.dns.id. id. 172800 IN NS b.dns.id. id. 172800 IN NS c.dns.id. id. 172800 IN NS e.dns.id. id. 172800 IN NS sec3.apnic.net. ;; Received 289 bytes from 2001:503:c27::2:30#53(2001:503:c27::2:30) in 310 ms go.id. 43200 IN NS b.dns.id. go.id. 43200 IN NS c.dns.id. go.id. 43200 IN NS d.dns.id. go.id. 43200 IN NS e.dns.id. ;; Received 189 bytes from 202.155.30.227#53(202.155.30.227) in 28 ms polri.go.id. 43200 IN NS ns2.polri.go.id. polri.go.id. 43200 IN NS ns4.polri.go.id. polri.go.id. 43200 IN NS ns3.polri.go.id. polri.go.id. 43200 IN NS ns1.polri.go.id. ;; Received 165 bytes from 103.19.177.177#53(103.19.177.177) in 192 ms polri.go.id. 38400 IN A 120.29.225.249 ;; Received 45 bytes from 120.29.231.231#53(120.29.231.231) in 13 ms Any idea what is the issue ? this 2 server are in the same subnet. I've double check that no routing issue. Thank you in advanced. Regards, Franky
