For example, if namebench tells you that Google, Facebook, and Paypal are hijacked, it probably just means that these companies have added IP addresses to their domain that namebench isn’t up to speed on. But in my experience, most of these are false positives. These notes can sometimes flag potential hacking, censorship or hijacking attempts. If you drill down deeper into the results, you’ll get some notes on the actual domain name resolutions. But after I read your answer I digged a bit more and found an excellent explanation here: - quote: Just a small comment first: "namebench" is supposedly a DNS benchmark-script and I'm also not very familiar with it. 8.8.8.8 and 8.8.4.4 as DNS servers instead of the default (from my ISP). Oh, thanks a lot, great suggestion about just setting the DNS and I imagined it would be a good idea to repeat the test, with e.g. There are too many errors/warnings, I think. Question: Is my ISP blocking public DNS-servers or? I don't understand it. Here's a link to the namebench-output (full output): All nameservers have warning: is hijacked: (likely a false positive) All nameservers have warning: is hijacked. (likely a false positive) All nameservers have warning: No answer (NXDOMAIN): static.ak. * Internal 192-1-1 failed test #2/7: Too many warnings (7), probably broken. * DynGuide failed test #2/5: Too many warnings (7), probably broken. Trying again with 6 threads (slow)",ĥ05 of 4514 servers are available (duration: 0:32:47.630533)ĭynGuide-2 failed test #1/5: static.ak.: No answer (NXDOMAIN): static.ak. "How odd! Only 11.2 percent of name servers were pingable. I don't understand the output from namebench.py - especially errors/warning about servers being "hijacked", too many warning, things appear broken (see the list below + attached). I tried the namebench.py script because I wanted to use another DNS-server than my ISP's (default) dns-servers. I want to setup my main router to use DNS-servers that don't belong to my ISP. The gateway at 192.168.1.1 also acts as a DNS-server with the following upstream DNS: I think it's because 192.168.1.1 is also the default gateway.
I have the following hypothesis: I have 2 routers, 1 gateway, the other WAP. Posted: Tue 21:32 Post subject: namebench.py - Is my ISP blocking public DNS-servers?
