Updating the root hint

You can find the root hints on the IANA website – there’s an FTP link to the file containing root hints, as well as an HTTP link (

I thought simply entering this in the ‘Copy from Server’ window should suffice but it doesn’t. The window says it wants a server name or IP address so I removed everything above except the server name and then clicked OK. Server: win-dc03.rakhesh.local Address: 10.50.0.22 Non-authoritative answer: (root) nameserver = a.(root) nameserver = b.(root) nameserver = c.(root) nameserver = d.(root) nameserver = e.(root) nameserver = f.(root) nameserver = g.(root) nameserver = h.(root) nameserver = i.(root) nameserver = j.(root) nameserver = k.(root) nameserver = l.(root) nameserver = m.a.internet address = 198.41.0.4 My DNS server doesn’t have an authoritative answer (notice the output above) because it only has the info that’s present with it by default.

The real answers could have changed by now (and it often does – the root hints list that these servers come with can have outdated entries) but that’s fine because it has some answers at least.If I were to input this server’s name or IP address to the ‘Copy from Server’ dialog above, that DNS server gets the root hints from this DNS server and updates itself.
