Multi Server DNS Lookup (DNS Lookingglass)

This tool will pick DNS servers located in different countries to lookup a hostname. Servers labeled as "Global" are 1.1.1.1, 8.8.8.8, 9.9.9.9. It is normal for some DNS servers to return no responses (we use a fairly short timeout). For each country, we will use three different DNS servers.

This feature can also be used via our API: https://isc.sans.edu/api/dnslookup/[hostname].

Feedback welcome. Please use the bug reporting on the left or our contact form.
