OK, I just did this, and got the error.
Your NAT has a built-in DNS proxy. We sent it a DNS request and our
server received it from 220.127.116.11.
Some or all specialized DNS types checked are not properly interpreted
by the NAT's DNS proxy. The following tested queries were blocked/failed:
* RTYPE=169 (deliberately unknown) records.
18.104.22.168 is cmbg-dnsany-1.server.virginmedia.net. which makes
sense, as my ISP is viginmedia. I'm very sure that a query for RTYPE=169
will have been forwarded Ok by dnsmasq, so maybe the problem is at the
Is there a command line tool that will generate these queries simply?
dig only sends queries whose name it knows.
The ID of the netalyzer run was 43ca208a-28815-3a04eee7-dbda-4220-84b4
if that's useful.
