Hmm. First, make sure that it isn't running (service local_unbound stop, etc).
Then look at your /etc/resolv.conf -- unbound tends to rewrite that on initial
startup, taking some of it's settings and inserting itself into the middle as a
caching DNS server. At the very least, you want something like this:
nameserver 8.8.8.8
I think the default DHCP client stomps all over /etc/resolv.conf fairly well,
but see what options are in there (for example, options for domain-name-servers
and domain-name). The stock /etc/dhclient.conf is all comments.
I have issues with the DNS results my ISP returns to me, but setting up a cache
or using sites like 8.8.8.8 (google public DNS, if you don't mind feeding the
beast) fixes that.
For something deeper, what is your /etc/host.conf? Mine is this:
# Auto-generated from nsswitch.conf
hosts
dns
That lets your /etc/hosts contents override DNS, which is often a good thing.
By default, your /etc/hosts should be pretty much all comments except for
these two lines:
[grep -v '^#' /etc/hosts]
::1 localhost localhost.my.domain
127.0.0.1 localhost localhost.my.domain
