DNS Poisoning Fixes: Are Your Country’s ISPs Still Vulnerable?

Following my posts on DNS testers to make sure that your ISP is not vulnerable to the DNS poisoning problem that is now in the wild, Dan Kaminsky has a video of the progress of the DNS fixes around the world. It’s embedded below.

The red spots are unpatched, yellow are patched but with the NAT causing problems, and green are the fully patched areas with properly working DNS servers.

If you have not checked whether your ISP’s DNS servers are fully patched, see my previous posts on DNS-Oarc’s DNS tester and Dan Kaminsky’s DNS server checker.
