Using nsupdate for dynamic DNS TSIG Updates To update a DNS server dynamically using TSIG for authorization, run nsupdate by doing the following:

$ nsupdate -d
> server update.dyndns.com
> zone $ZONE
> key $KEY_NAME $KEY_HMAC
> update add $HOST.$ZONE 60 A 10.0.0.1
> send
> quit

For dynamic DNS hosts, $ZONE should be the third level DNS name like myhost.dyndns.org

But it doesn't explain what $HOST is expected to be?

I would expect it to be the name of the host e.g. myhost as the zone would be dyndns.org.

    Right. nsupdate requires the FQDN here. For instance update add myserver.example.com 60 A 203.0.113.47 – Michael Hampton Sep 10 '13 at 5:53
