The second and third lines in host are for the ipv6 address (AAAA record) and the mail server (MX record). These fail with a timeout. It is likely that the authority server for these domains does not respond to AAAA and MX records and unbound copies this to you. If the authority for these domains answers for AAAA and MX, even if that is an empty packet without an answer, then you would not get a timeout here. > Infos about our environment: > > - Ubuntu 12.04 LTS - Unbound v1.4.16-1 - Squid Proxy > > If we try to access these domains through the proxy we get an dns > error. It should be able to get the ipv4 address, not sure why it fails.
