/usr/bin/unbound-host: invalid option -- '-'
Usage: unbound-host [-C configfile] [-vdhr46] [-c class] [-t type]
[-y key] [-f keyfile] [-F namedkeyfile] hostname
Queries the DNS for information.
The hostname is looked up for IP4, IP6 and mail.
If an ip-address is given a reverse lookup is done.
Use the -v option to see DNSSEC security information.
-t type what type to look for.
-c class what class to look for, if not class IN.
-y 'keystring' specify trust anchor, DS or DNSKEY, like
-y 'example.com DS 31560 5 1 1CFED8478...'
-D DNSSEC enable with default root anchor
from /etc/unbound/root.key
-f keyfile read trust anchors from file, with lines as -y.
-F keyfile read named.conf-style trust anchors.
-C config use the specified unbound.conf (none read by default)
pass as first argument if you want to override some
options with further arguments
-r read forwarder information from /etc/resolv.conf
breaks validation if the forwarder does not do DNSSEC.
-v be more verbose, shows nodata and security.
-d debug, traces the action, -d -d shows more.
-4 use ipv4 network, avoid ipv6.
-6 use ipv6 network, avoid ipv4.
-h show this usage help.
